居民用户参与电网调峰激励智慧用能策略研究

Research on smart energy consumption strategy of residents participating in peak load regulation

以实现居民用户智慧用能为着眼点,提出一种居民用户参与电网调峰激励智慧用能策略。首先,根据家用电器的负荷特性将居民用户用电负荷分为4类,并建立其相应数学模型;然后,综合考虑时间、用电满意度以及电费满意度约束建立居民用户用电成本优化模型;同时,考虑传统分时电价难以调动居民参与电网削峰填谷积极性,根据余弦相似度建立调峰效果评估模型,基于居民调峰贡献度提出市场激励机制;最后,将调峰效果引入夏普利值(Shapley value)分配中,建立居民用户与电网公司的合作博弈模型。仿真结果表明:所提策略能有效降低家庭用电成本,同时促进居民用户积极参与电网调峰。

Focusing on enabling smart energy consumption for residential users,a smart energy strategy with incentives for residential users to participate in grid peak shaving is proposed.According to the load characteristics of household appliances,residential loads are classified into four categories,and corresponding mathematical models are established.Considering time constraints,electricity satisfaction constraints,and electricity bill satisfaction constraints,an optimization model for residential electricity consumption cost is established.Given that traditional time-of-use electricity pricing is inadequate in motivating residents to participate in grid peak shaving and valley filling,a peak shaving effect evaluation model is established based on cosine similarity,and a market incentive mechanism is proposed based on residents'contribution to peak shaving.Finally,the peak shaving effect is introduced into the Shapley value allocation to establish a cooperative game model between residential users and grid companies.Simulation results demonstrate that the proposed strategy can effectively reduce household electricity consumption costs while promoting active participation of residential users in grid peak shaving.
