Abstract

Abstract: In order to study the interaction between the price of electricity in microgrid and the price of electricity sold in distribution network, and to realize the reasonable pricing of the interactive electricity quantity between the microgrid and the distribution network, this paper proposes a pricing method to maximize the benefits of both the microgrid and the distribution network. Through discussion on the impact of the construction and operation of microgrid on distribution network and microgrid operators, the cost-benefit model of microgrid and the comprehensive benefit model of distribution network are established to quantitatively evaluate each cost-benefit. Then the cost-benefit is divided into capacity cost-benefit and electricity cost-benefit, and the optimal benefit models of microgrid and distribution network are established, respectively. The optimal model obtains the influence of in-house price on the optimal benefit of microgrid and distribution network, and compares and analyses the reasonable range of interactive pricing between microgrid and distribution network under different in-house price of microgrid through a specific example of microgrid, which verifies the feasibility of the proposed model.

Key words: microgrid, distribution network, cost-benefit analysis, power market, interactive electricity price
