Analysis of the reliability of photovoltaic-microwind based hybrid power system with battery storage for optimized electricity generation at Tlemcen, north west Algeria
This article considers designing of a renewable electrical power
generation system for self-contained homes away from conventional grids.
A model based on a technique for the analysis and evaluation of two solar
and wind energy sources, electrochemical storage and charging of a housing area is introduced into a simulation and calculation program that aims
to decide, based on the optimized results, on electrical energy production
system coupled or separated from the two sources mentioned above that
must be able to ensure a continuous energy balance at any time of the day.
Such system is the most cost-effective among the systems found. The wind
system adopted in the study is of the low starting speed that meets the
criteria of low winds in the selected region under study unlike the adequate
solar resource, which will lead to an examination of its feasibility and profitability to compensate for the inactivity of photovoltaic panels in periods
of no sunlight. That is a system with fewer photovoltaic panels and storage
batteries whereby these should return a full day of autonomy. Two configurations are selected and discussed. The first is composed of photovoltaic
panels and storage batteries and the other includes the addition of a wind
system in combination with the photovoltaic system with storage but at
a higher investment cost than the first. Consequently, this result proves
that is preferable to opt for a purely photovoltaic system supported by the storage in this type of site and invalidates the interest of adding micro wind
turbines adapted to sites with low wind resources.
