Hybrid System Optimal Designing Using New Ant Lion Optimization Algorithm Considering Cost/Reliability Evaluation

In this paper a hybrid system based onphotovoltaic (PV) arrays and wind turbine (WG) and fuel cell(FC) consists of electrolyzer (EL) and hydrogen storage tank(HST) is designed optimally to supply the system load. Theoptimal hybrid system designing is implemented by consideringthe annual system cost minimizing and reliability indices. In thispaper, ant lion optimizer (ALO) that is a new intelligent methodis applied to solve the optimization problem. In this paper due toimportance of load supply in hybrid power generation system,variation of loss of power supply probability range (LPSP) isevaluated on system costs, reliability indices, HST expectedenergy and system optimal configuration. The results show thatconsidering the load loss in optimal designing, increase theannual system cost and also with decreasing in LPSP, the loadloss annual cost is decreased and the reliability indices areimproved.
