摘要: 为研究微电网上网电价与配网售电电价的交互关系,实现二者交互电量的合理定价,提出了一种实现微电网和配电网双方效益最大化的电价制定方法。通过探讨微电网建设运营对配电网和微电网运营商带来的影响,建立微电网的成本效益模型和配电网的综合效益模型,对各项成本效益做出量化评估;然后将各项成本效益划分为容量类成本效益与电量类成本效益,分别建立微电网与配电网的最优效益模型;最后通过求解最优模型,得到微电网网内售电电价对微电网和配电网最优效益的影响,并通过具体的微电网算例,对比分析不同微电网网内售电电价下微电网与配电网交互电价的合理范围,验证了所提模型的可行性。

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
