Optimal Size of the Hybrid Systems Wind, Photovoltaic, Diesel Generator and Battery in Isolated Micro-Grid from the Network

Energy crisis is one of the issues that is of great interest to today s societies. Optimizing the energy system in terms of resource diversity and the size of each unit can greatly improve the economic and technical efficiency of the feeding system. In this paper, a feasibility study and also economic optimization for a system independent of the network for the central regions of Iran is presented (Case Study of Varzaneh Region). HOMER software has been used for measurement as well as optimization tools. Renewable and non-renewable energy sources (fossil fuels), energy storage methods, and the ability to use them on a cost-efficient basis. Sensitivity analysis is performed for wind speed, solar radiation and fuel costs. An agricultural farm with an energy consumption of 10 kWh/d and a maximum load of 1 kW load is considered as an autonomous load.
