Opis:
The paper adds to the discussion of social costs of financial crises through theoretical elaboration, arguing for the position that supporting the stability of financial systems, if combined with public confidence in financial markets and banking, leads to a reduction of social costs by reducing the frequency of crises associated with the long-term development of the financial sphere in the world. Following the theoretical function proposed by Adrian, Covitz and Liang [2014], the author elaborates that prudential regulation may lower the social costs of crises. This calls for an active role of regulating the financial sector and that of the central banks, as the preferred sensitivity of the financial system to shocks may be achieved by prudential regulation and the increasing of transparency of the system, as well as by the management of social perception of stability (security) of this system. The paper postulates the abovementioned relation by reviewing selected empirical studies and framing the discussion in theoretical elaboration on social costs and financial stability.

Opis:
This paper presents a microelectronic emulation approach for high-speed power system computation. First, the problems of existing power system simulators are detailed. This shows that microelectronic emulation is a possible solution for solving the speed problems of existing simulators. Second, this paper presents one specific emulation approach, the so-called AC emulation approach. The ultimate objective of the AC emulation approach is the realization of a power system emulator which reproduces simultaneously a large number of phenomena of different time constants or frequencies with a much higher speed than real time. Frequency dependence of the elements is preserved and the signals propagating in the emulated network are the shrunk or downscaled current and voltage waves of the real power network. The models of the power network components are detailed. Special attention is paid to the generator model which was shown to introduce a systematic error. This systematic error is quantified, analyzed and optimized. Moreover behavioral simulation results confirm the feasibility of this approach which in turn lays the foundation for such an emulator.

Opis:
Goal – The authors undertake to assess the scale and form of anti-crisis state assistance in the context of restoring the stability of the financial system in the EU. Such assistance is a form of intervention undertaken independently by EU Member States under the conditions of admissibility applicable in the EU. The applied instruments include: state aid (discussed in detail in this paper) and financial assistance on general terms applied in the form of unconventional instruments. The authors attempt to answer two basic questions: Was anti-crisis assistance necessary in the EU in order to maintain the stability of the financial system? What are the long-term consequences of implementing such measures at the EU level and in individual EU Member States? Research methodology – The study uses the method of analysis of partial phenomena and identification of causal changes occurring in the financial system. On this basis, theoretical inference is carried out allowing to determine whether the anti-crisis measures used by EU financial policy have brought tangible results for the financial system and the real economy. In order to formulate final conclusions, available statistical data and the results of research conducted on an international level are analyzed. Next, the current value of financial aid is estimated and the adopted assumptions and efficiency of the implemented instruments of state financial policy are analyzed and assessed. Score – In view of the objective and scope of the conducted research, it is expected that the obtained results will allow the authors to identify the scale of public aid and the assistance provided in the form of unconventional financial policy instruments implemented during the global financial crisis. This approach will make it possible to perform an appraisal of the use of selected mechanisms for stabilizing the financial system. The conducted research should enable the authors to assess the impact of anti-crisis aid on the state of public finances and the stability of the market financial system.

Opis:
The aim of the study was to analyze the stability of the financial system to answer the question if this stability has characteristics of the public good. If the answer is positive it determines the specific role of the state in the field of financial system stability. The paper presents also a theoretical aspects of the possibility to qualify the financial system to the category of public goods. The authors conclude that if the stability of the financial system is not in the strict sense the public good (or at least the common good) it should consider the scope and degree of responsibility of the state and its institutions for action aimed at stabilizing financial stability. The arguments presented in the paper demonstrate, however, in favor of the recognition of the stability as a public good. It is therefore a mandate for public sector interventions and interference in such a way as to minimize the risk of destabilization.

Opis:
The deposit guarantee system in Poland was devised at the time of the economic transformation. Its creation resulted from a difficult situation in the banking sector, and so it was meant to be an antidote to clients’ problems associated with the insolvency of collapsing banks and with adjusting to European community law. The aim of this work is to present the Bank Guarantee Fund-an institution that is part of the financial safety net, whose main task is to protect the interest of depositors and to ensure the banking system’s stability. The paper looks at some aspects of the growing interest in bank deposit insurance schemes and lively discussions on the subject during a crisis in banking markets. In response to the crisis that started in the subprime lending market in the USA and spread to other segments of the financial markets as well as to other countries, the ECOFIN made a decision to increase the existing guarantee limits for individual persons and to speed up the payout of guaranteed funds. The above changes were aimed at strengthening the security of clients and increasing confidence in the banking sector.

Opis:
W artykule omówiono zagadnienia związane ze stabilnością sieci elektroenergetycznej, przeznaczenie i zasadę działania urządzenia DA-Box 2000 oraz wykorzystanie go do monitorowania stabilności sieci elektroenergetycznych. Doświadczenia niemieckie wskazują, że badanie stabilności sieci ma coraz większe znaczenie w praktyce z powodu gwałtownego wzrostu udziału nieliniowych źródeł i odbiorów energii w systemie elektroenergetycznym. Przyrząd DA-Box 2000, poprzez zaawanasowaną analizę napięć i częstotliwości, jest w stanie wykryć groźbę utraty stabilności przez system elektroenergetyczny spowodowany na przykład lawiną napięcia lub częstotliwości. Według danych producenta urządzenia te pracują z powodzeniem w kilkunastu krajach na całym świecie.
The power system is a complex system in which, except the usual linear elements, there are more and more nonlinear and restless power generating and loading devices. This causes that even in the normal working conditions, besides the basic harmonic (50 Hz) of current and voltage there are more and more higher harmonics and subharmonic. Higher harmonic content generally refers to the quality of energy, while subharmonic, especially low frequency oscillations of several Hz or even less than 1 Hz, can be used for power system stability testing. Unfortunately, so far they are basically not used either in the power system protection or in the power system control. This paper presents issues related to the stability of the power grid, the purpose and principle of operation of the DABox 2000 and its use to monitor the stability of the power grid. German experience indicates that the study of network stability is becoming increasingly important in practice due to the rapid increase in the share of nonlinear sources and energy load in the power system. The DA-Box 2000 device, using its advanced voltage and frequency analysis, is able to detect the threat of power system failure due to, for example, a collapse of voltage or frequency. According to the manufacturer's data, these devices work successfully in over a dozen countries around the world.

Opis:
The paper concentrates on changes in the public finance sector in recent years: a topic of great importance from the viewpoint of maintaining stability of finan‑ cial system and from both national and EU perspective. The effects of the current financial crisis have stressed the need for action to reduce the growing deficit and public debt. Debt crisis shows that it is necessary to conduct an effective fiscal con‑ solidation to put and maintain economies of many countries on a path of sustain‑ able growth. The paper begins with a brief presentation of theory. In the following part, the paper discusses structural and cyclical causes of the rising debt. Changes in the legal environment, including key issues, were also discussed. Fiscal rules, fiscal councils and the fiscal pact were therefore analyzed in detail. The authors furthermore pay attention to certain limitations and weaknesses of fiscal policy, stressing the necessity to look at the economy from a broader perspective and to use other tools and instruments of state policy. The study includes recent data on GDP, the budget deficit, public debt and expenditure and revenue in the EU.

Opis:
The high content of nitrates in drinking water leads to serious diseases. The creation of biofiltering devices with the longest time of their operation between preventive flushes is extremely important. The purpose of this study was to investigate the features of the functioning of the developed U-shaped submersible denitrifying biofilter during its long-term operation in the piston filtration mode. The denitrification of water by using the method of displacement (piston) biofiltration in a submersible small U-shaped biofilter with immovable carriers of attached microflora in its filter load was studied. As a result, clogging of the pore space of the biofilter in the zone of excess bacterial nutrition is prevented and the vital activity of bacteria is maintained in places where there is no nutrient substrate. It has been shown that, due to adaptive mechanisms, denitrifying bacteria convert nitrate ions into gaseous nitrogen, consuming extracellular polymeric substances. The rate constants of the reaction of reduction of nitrates to molecular nitrogen in different zones of the biofilter under different filtration modes were determined. The activity of the microflora inside the biofilter quickly returns to its original level when a full-fledged external nutrition is resumed. The efficiency of nitrate to nitrogen conversion in the studied biofilter is 94.2±8.9%.

Opis:
In this paper, a novel bacterial foraging algorithm (BFA) based approach for robust and optimal design of PID controller connected to power system stabilizer (PSS) is proposed for damping low frequency power oscillations of a single machine infinite bus bar (SMIB) power system. This paper attempts to optimize three parameters (Kp, Ki, Kd) of PID-PSS based on foraging behaviour of Escherichia coli bacteria in human intestine. The problem of robustly selecting the parameters of the power system stabilizer is converted to an optimization problem which is solved by a bacterial foraging algorithm with a carefully selected objective function. The eigenvalue analysis and the simulation results obtained for internal and external disturbances for a wide range of operating conditions show the effectiveness and robustness of the proposed BFAPSS. Further, the time domain simulation results when compared with those obtained using conventional PSS and Genetic Algorithm (GA) based PSS show the superiority of the proposed design.

W referacie przedstawiono zasady działania szybkiego zaworowania (fast-valving) i korzyści stosowania tej techniki we współczesnych systemach elektroenergetycznych. Omówione zostały modelowe badania skuteczności FV w warunkach KSE oraz analiza możliwości wprowadzenia FV na bloku 560 MW El. Kozienice, wykonane w ramach I etapu pracy IASE Wrocław i Instytutu energetyki Oddział Gdańsk dla PSE SA, której przedmiotem jest analiza możliwości zastosowania FV w pracujących w KSE i planowanych do przyłączenia dużych blokach konwencjonalnych.
Fast-valving assists in maintaining system stability following a severe transmission system fault by reducing the turbine mechanical power. Fast-valving consists in rapid closing and opening of steam valves in adequate manner to reduce the generator accelerating power following the recognition of a severe fault. FV can be an effective and economical method of meeting the performance requirements of power system in the presence of the increase of wind and solar generation in power system and newly connected large thermal units and delaying of building new transmission lines. The principle of fast-valving and advantages of application this technique in large steam turbine units were presented in the paper. Effectiveness of fast-valving in enhancing the stability of Polish Power Grid was analyzed. Feasibility study of fast-valving application in the 560 MW unit in Kozienice Power Station (EW SA) was discussed.
