摘要
针对微电网中源、荷波动和匹配性较差以及现货市场电价不确定问题,综合考虑电价型与激励型需求响应各自的优势,提出了一种现货市场下计及用户需求响应弹性差异的微电网运营商优化运营模型及其求解方法。在日前阶段,建立了计及负荷差异化电量电价弹性矩阵的价格型需求响应模型;在实时阶段,构建了符合微电网运营商和用户利益关系的主从博弈模型,并采用改进粒子群算法进行求解。此外,基于不同用户在同一时段负荷响应弹性差异化的特征,首次将激励因子的概念引入到激励型需求响应中,使得积极响应的用户能享受到更高的激励价格。仿真结果表明,所提模型增强了削峰填谷效果,源、荷匹配性较差的问题也得到了一定改善,并且微电网运营商和用户均可从中获取额外的经济收益;同时,所提出的动态激励价格在保证公平性的同时,进一步提高了微电网运营商和用户的总社会效益。
Aiming at the problems of source and load fluctuations and poor matching of microgrid and the uncertainty of spot market electricity price,we comprehensively took into account the respective advantages of electricity price and incentive demand response,and proposed an optimized operation model and its solution method for microgrid operator considering the difference in user demand response elasticity under the spot market.In the day-ahead stage,a price-based demand response model which considers the load-differentiated electricity price elasticity matrix was established.In the real-time stage,a Stackelberg game model that conforms to the interests of microgrid operators and users was constructed,and an improved particle swarm algorithm was used to solve the problem.In addition,based on the characteristics of different users’load response elasticity at the same time period,the concept of incentive factors was introduced into incentive-based demand response for the first time,so that users who actively respond can enjoy higher incentive prices.The simulation results show that the proposed model enhances the effect of peak shaving and valley filling,the poor matching of source and load has also been improved to some extent,and microgrid operators and users can obtain additional economic benefits from it.Meanwhile,the adoption of the proposed dynamic incentive price,while ensuring fairness,may further improve the total social benefits of microgrid operators and users.
