Energy management in a real microgrid with hydroelectric power plant and battery storage unit

The paper presents a simulation of the energy storage power control following predefined charge characteristics. The demand of local power consumers exceeding the given margin should be covered by the local generation (hydroelectric power plant) and from an energy storage system. The energy storage unit can be charged by the energy generated by the power plant and the energy from the power system. A storage control scenario was developed, where the main goal is to limit to the set level of power exchanged with the power system. Simulation calculations were carried out using data recorded in a real power system. The paper shows the influence of selection of energy storage unit characteristics and different generation cases on the operation of the whole system.
