Microgrid Comprehensive Economic Dispatch Based on Generation-load Interaction

Abstract

The generation-load interaction is an effective way to utilize the generation and load side resources. Aiming at the uncertainty of the schedulable range of incentive-based DR’s load reduction, the upper limit of capacity reduction is determined by baseline load and forecast load based on the economic scheduling model, and the load reduction cost model of incentive-based DR is established. Considering the influence of the electricity price on electricity consumption, a load guidance cost model of price-based DR is established. According to the incentive load reduction cost and price load change cost and each unit model, a comprehensive model of day-ago microgrid dispatch is established. The example analysis verifies the validity of the comprehensive model. The scheduling accuracy can be guaranteed by modifying the reduction range of the incentive-based DR, and the rationality of the guided price load can be guaranteed by adjusting the price-based DR.
