Opis:
With Growing Concerns About Voltage Profile And Power Factor At Distribution Networks, The Capacitor Banks Are Invariably Installed For Reactive Power Compensation. The Reactive Power Supplied By Capacitor Banks Is Proportional To Square Of Their Rated Loading Voltage. Capacitor Banks Eventually Increase The Loading Capacity Of Feeders, So As To Supply More Customers Through Same Line Section. Capacitor Banks Can Be Installed Anywhere On The Network. The Idea Of This Paper Is To Reduce Total Power Loss And Ensure Greater Availability Of Capacitor Bank Installed At 132 Kv Grid Station Qasimabad Hyderabad, For Reactive Power Compensation, Even Under Worst Conditions On Distribution System. This Is Achieved By Enhancing Its Location And Size. At Present Capacitor Bank Of Full Size, I.E. Of 1.21 Mvar Is Installed At 11 Kv Bus Of 132 Kv Grid Station Qasimabad Hyderabad. Moreover This Paper Suggests Small Sized Capacitor Banks That Would Be Installed At Different Feeders Instead Of One Large Size Capacitor Bank At 11 Kv Bus. The Voltage Profile And Power Losses With Present Sized Capacitor Bank And The Proposed Small Sized Capacitor Banks Are Compared In This Work. The Distribution Network Has Been Simulated By Using MATLAB .

Opis:
The issue of ORPD (Optimal Reactive Power Dispatch) for enhancing security and economy of a power system has been given substantial consideration in recent days. The major inspiration behind deploying an ORPD system for enhancing power system efficiency is to reallocate the RP (reactive power) in such a manner that power loss be minimized, and voltage profiles get enhanced. Hence, this paper concerns the major objectives, namely, reduction of power loss and voltage deviation that are related to solving ORPD problem under unbalanced condition. To attain these objectives, an amalgamation of two algorithms, called CS (Cuckoo Search) and GWSO (Glow Worm Swarm), is adopted for optimizing, and hence the proposed model is referred to as CP-GWSO. This algorithm functions with the control parameters, namely load reactance, voltage and transformer tap settings that are tuned to attain the optimum outcome. The entire empirical part of the investigations is performed on two IEEE standard test bus systems, the IEEE 14 and the IEEE 39 bus systems. Finally, the proposed scheme is compared to the conventional methods, and its efficiency is confirmed.

Opis:
High distribution system power-losses are predominantly due to lack of investments in R&D for improving the efficiency of the system and improper planning during installation. Outcomes of this are un-designed extensions of the distributing power lines, the burden on the system components like transformers and overhead (OH) lines/conductors and deficient reactive power supply leading to drop in a system voltage. Distributed generation affects the line power flow and voltage levels on the system equipment. These impacts of distributed generation (DG) may be to improve system efficiency or reduce it depending on the operating environment/conditions of the distribution system and allocation of capacitors. For this purpose, allocating of distributed generation optimally for a given radial distribution system can be useful for the system outlining and improve efficiency. In this paper, a new method is used for optimally allocating the DG units in the radial distribution system to curtail distribution system losses and improve voltage profile. Also, the variation in active power load in the system is considered for effective utilization of DG units. To evidence the effectiveness of the proposed algorithm, computer simulations are carried out in MATLAB software on the IEEE-33 bus system and Vastare practical 116 bus system.
