Design and analysis of Grid integration system for renewable energy sources
Project Area of Specialization
Project Summary
In this project a hybrid power system based on dc coupled hybrid PV/Fuel Cell/Battery power system is made that supports the local grid. Part of the local active and reactive power demand is supplied by the hybrid power system. Consequently, the grid operates at or near unity power factor at the point of common coupling (PCC). The hybrid power system normally operates under load following mode where only the hybrid power system meets the local demand. For loads beyond the maximum capacity of the hybrid power system and inverter, the grid supplies the rest of the local power demand. This helps to relieve transmission line congestion problem by producing most of the local demand locally, reduce transmission line losses especially for loads very far from the utility grid. An effective power flow control strategy is developed to manage the power between the hybrid power source and the local grid. The main idea of the control strategy is to utilize the PV energy to the maximum by using maximum power point tracker (MPPT) and the rest of the power that cannot be met by the PV should be supplied by the fuel cell. During peaking demand period where the combined power output of the PV and fuel cell is insufficient to meet the power, the battery energy storage takes on the peaking part of the demand. The power flow control strategy keeps the battery charged for the next peaking period from the PV and fuel cell.
