Optimal Sizing of an Isolated Hybrid Wind/PV/Battery System with Considering Loss of Power Supply Probability

In recent years, renewable energy technologies such as wind and solar have had significant growth and they can be used close to the consumption centers in order to remove high-voltage transmission lines. Using these sources with a power storage in the form of a hybrid system provides the increase of system reliability. The importance of achieving to the proper configuration of off-grid hybrid energy systems in order to reduce the cost of implementation and load continued support and system reliability, make the use of powerful software for optimization necessarily. Therefore, in the present study HOMER software is used to establish the best possible situation between cost and reliability (loss of power supply probability (LPSP)), hybrid energy system (consisting of wind turbines, photovoltaic panels and batteries) in the off-grid form to provide a load power remote from the grid. Data of load, wind speed and solar radiation are definite for Kurdeh village, the central district of the Larestan city. The system costs consist of initial investment and maintenance of equipment replacement. The considered prices are real and the used equipment’s are available in the market.
