Predictive energy management and control system for PV system connected to power electric grid with periodic load shedding

摘要

Power Electric Grid (PEG) tied Photovoltaic (PV) plus Battery Energy Storage Stations (BESS) based Micro Grids (MG) are controlled and operated inefficiently with Conventional Energy Management and Control (CEMC) schemes. CEMC schemes, (1) leave these systems on the mercy of weather with either energy shortage resulting in loss of load (LOL) or requiring huge BESS resulting in high capital and Operation & Maintenance costs, (2) cause curtailment and thus wastage of surplus PV energy (PVE), and (3) increase energy cost due to unnecessary charging of BESS from PEG. LOL and surplus PVE wastage grow even further when MG are connected to a weak PEG with periodic load shedding.
