The optimal use of stationary battery storage in a prosumer power system

In this paper, optimization model for energy management in the prosumer power system is presented. Previous passive electricity consumers by integrating the renewable energy sources in their possession become consumers with their own generation, or so-called prosumers. The optimization model gives the optimal schedule of a stationary battery storage utilization and charging schedule of the battery in electric vehicle (EV) according to expected production from photovoltaic (PV) power plant and household consumption. The goal of the optimization model is to minimize electricity cost for prosumer power system. The optimization model is applied on a case study to show general features of the model. The case study refers to an assumed prosumer power system consisting of a 10 kW PV power plant, stationary battery storage rated capacity of 20 kWh and a household load considering charging the battery in EV. The simulations are performed for working day and one weekend day. The results show savings in electricity costs when the stationary battery storage is used in the prosumer power system.
