Power Balance Strategy based on Orderly Electricity Consumption with Demand Response

Power balance strategy is more critical than before to the reliability and safety of the new grid with a growing penetration of intermittent renewable energy. A comprehensive methodology based on orderly electricity consumption (OEC) and demand response (DR) is proposed in this work to deal with power tight balance and power deficiency. First, DR is employed to improve the load profile by guidance of electricity price. Then, orderly consumption power (OCP) is determined and allocated over the subsystems according the load sizes and types. Furthermore, subsystem OCPs, including power shifting, averting and rationing are specified. At last, reliability assessment is implemented to review the practicability of the power balance strategy. The effect of the proposed methodology is verified by case studies.
