Energy Storage Operation with Renewable Generation for Energy Self-reliance in Smart Grid

As the renewable generation facilities are increased, the power system is required to manage balance between supply and demand, and to maintain its stability. In this paper, for energy self-reliance of housing complex, a method for capacity design of renewable generation and an operation policy for an energy storage are proposed. Load profiles from the housing complex are merged and combined with a generation profile, and the energy storage operates to reduce peak load or generation power based on the profile. Through a simulation by Python program, the energy self-reliance and the effect of peak reduction were verified.
