Optimal Energy Management of Isolated Micro-Grid Including Solar and Diesel Power with Pumped Storage

Recently, pumped storage hydropower is used in the agricultural industry and isolated rural micro-grid. On the other side, a diesel generator usually does not operate in optimum point in isolated power supply. Therefore, it can be used in joint with other energy sources such as photovoltaic and energy storage system which develop an ideal option for autonomous power generation in islanded mode. Hence, this paper intends to present an optimal operation and energy management method for a hybrid micro-grid with study on day-ahead scheduling. In this paper, optimal operation of hybrid micro-grid including of photovoltaic, pump as turbine system, and diesel generator are considered. The optimal energy management minimize the fuel cost of diesel generator, annual operating cost as well as the balance between generation and load in different seasons. Aiming to this purpose, three famous optimization algorithms, namely artificial bee colony (ABC), particle swarm optimization (PSO) and imperialist competitive algorithm (ICA), are used to determine the optimal diesel generator generation, pumped storage operating mode, pumping and turbine real power in order to minimize the total operating cost for a day-ahead.
