A Supervisory Power Flow Controller for a Hybrid Power System

Abstract:

Hybrid power system presented in this work focuses on the combination of wind, solar, and energy storing systems for sustainable power generation. The output power of wind turbine is only available under a specific speed or higher. The solar energy varies hourly, daily and seasonally which depends on variation of solar irradiation. A generator-set with a battery bank can be integrated with the wind and PV-system to ensure the continuity of power supply for all conditions.The paper aims to model and simulate the transient and steady state behavior of a Solar-Wind hybrid power generation system together with energy storage bank. Besides, a supervisory power flow controller has been developed which determines a power source that is selected to operate in order to satisfy the load demand taking into account the sun irradiance and the wind speed. The energy storage bank may be used to store an excess of power from the renewable energy system (RES) that will be used when there is insufficient supplied power. If either the available power from the wind turbine or from the solar panels or both of them cannot satisfy the load demand the generator set system will be used to satisfy the load demand. The functionality of the presented Hybrid Power System has been successfully designed and simulated using Matlab/Simulink tool.
