RPS与偏差电量考核下考虑微电网群的售电公司盈利模型

可再生能源配额制（renewable portfolio standard， RPS）和偏差电量考核机制是近几年推出的2项重要电改政策，使售电公司面临着双重考核压力。为量化分析RPS和偏差电量考核对售电公司的影响，综合考虑可再生能源配额制与偏差电量考核机制，以售电公司利润最优为目标，构建了2种售电公司盈利模型，即售电公司独自经营盈利模型和售电公司与微电网群代理商合作的盈利模型。售电公司与微电网群代理商合作的盈利模型的提出是为降低RPS考核成本，减少偏差电量以及兼顾微电网群绿色环保、灵活可控等优点。文章利用广东省实际交易数据对比分析了售电公司在2种盈利模型下的最优利润。分析结果表明，售电公司与微电网群代理商合作，降低了RPS与偏差电量考核成本，提高了整体利润，基于夏普利（Shapley）值分配方法，售电公司与微电网群代理商的盈利均能达到最大，为售电公司的最优经营策略。

Profit Model of Power Retailer Considering Microgrid Group Under Renewable Portfolio Standards and Energy Deviation Penalty Mechanism

Renewable portfolio standards （RPS） and energy deviation penalty mechanism are 2 major power reform policies introduced in recent years， which have caused the power retailer to face double assessment pressure. To quantitatively analyze the impact of RPS and energy deviation penalty on power retailer， 2 profit models are constructed with the aim of optimal profit， comprehensively considering renewable portfolio standards and energy deviation penalty. One is that the profit model of power retailer operates independently， and the other is that the profit model of power retailer and the microgrid group agent alliance cooperate， considering the advantages of green， environmental protection， flexibility and controllability of microgrid group.Using the actual transaction data of Guangdong province， the optimal profit under the 2 business models of the power retailer are compared and analyzed. The analysis results show that the cooperation of power retailer and the microgrid group agent can reduce the cost due to assessment following RPS and energy deviation penalty， and can increase the revenue. Adopting the Shapley value distribution method， power retailer and microgrid group agents can achieve the maximum profit， which is the optimal business strategy for power retailer recommended in this paper.
