Demand Management System for OFF-Grid PV System

摘要

In an efficient and stabilized energy distribution system, proper synchronization between supply and demand is highly desired. OFF-grid PV system is playing vital role for fulfilling the electrical demand with solar power plant and DG synchronization. In the generation side, renewable energy sources are generally tied with DG to meet the peak demand and providing the reference voltage and frequency for string inverters. Due to the variable nature of the load, it creates lots of reverse power flow problems in DG, which lead to the system instability. Demand side management is using load and generation control for integration of PV power plant with DG in OFF-grid mode. The study is carryout at 75 kW power plant with synchronization of 125 kVA DG in real time for understanding the instability parameters and control of generation and load demand with DMS.
