Optimization and implementation of hybrid energy sources in remote and grid active microgrids –A case study for Indian scenario

摘要

Rapid growth in Indian economy has increased the demand of electricity at a very high rate. The difference between demand and supply is high which results in power shedding. To improve the power situation, promotion of micro grid along with distributed generation shall be encouraged. A flow chart is proposed for selection of sources based on techno-economic viability. In this paper various options of solar PV systems have been explored. Optimization of size and control strategies of solar PV with DG for both grid active microgrid and remote location has been designed. A large hospital and a remote school have been considered for this case study and a micro grid has been implemented with solar PV system. In this paper contactor based and MPPT based control has been adopted for power control. Based on the hospital and school constraints like critical loads, maximum utilization of solar power, uninterrupted power (enough reserve capacity in case of grid unavailability) etc, a 300 kW and 20 kW solar power plant is simulated using PV-Syst and Digsilent. Comparison of results is obtained with actual plant output.
