Design the Optimal Number of Components in a Grid-Connected Hybrid Power Generation System

Abstract

Hybrid power generation systems are an effective solution for the variable generated power of renewable energy sources. In this paper, a grid-connected hybrid power generation system including wind turbines, solar panels, wave generators and power storage batteries for a village in the Chabahar Bay in southeastern of Iran is optimally designed. The purpose of selecting this region is to investigate the economic feasibility of using wave generators in hybrid power generation systems. In the design, during various operating scenarios simulated with Homer software, adding power generation resources to the village will provide part of the required power locally, which will reduce the cost of purchasing electricity from the power grid, and even profitability is also achieved with the sale of electricity to the power grid. On the other hand, the reliability of power grid is improved in terms of the Loss of Power Supply Probability (LPSP) index.
