Abstract

This study proposes a segmented subsidy mechanism suitable for microgrid load interruption management. The mechanism is in the form of a fixed subsidized tariff, where the grid pays the microgrid a tariff subsidy and the microgrid pays the users at a variable subsidized tariff, which is used to subsidize the losses of the users' participation in load interruptions. The study obtained a variable subsidized tariff model and a microgrid load interruption revenue model based on the least squares fitting method, and proposed three load interruption management strategies, namely, free interruption, fixed interruption time, and fixed interruption power, so that participating parties can choose flexibly. A flock optimization algorithm is used to solve the problem of maximum interruption revenue of a typical microgrid containing interruptible loads with a segmented subsidy mechanism. Example results verify the feasibility and effectiveness of the proposed strategy.
