摘要

考虑到电网友好问题,为带有混合储能装置的需求侧能源社区(DSEC)开发了一种聚合能源互动和营销策略。整个机制是一个分层方案。在上层,聚合器负责通过基于博弈的能源调度和营销策略管理所有需求响应。在下层,每个用户级能源消费者(EP)通过能源路由器参与 DSEC 内部的聚合能源互动,追求其最佳能源经济目标。为了实现与主电网的协调运行,分层能源互动和营销模型中纳入了能源自平衡和电网友好标准。然后将双层非线性系统模型转换为单层混合整数线性规划模型,并采用塔布搜索-粒子群优化算法进行求解。案例研究表明,采用所提出的能源调度和营销策略后,终端用户端的能源成本大幅降低。在案例研究中,三个 EP 的能源成本分别降低了 3%、8% 和 3%。考虑到电网友好性,DSECA 的收入比以前增加了 28%,负荷率从 36.46% 上升到 48.15%。

Aggregated Energy Interaction and Marketing for the Demand Side with Hybrid Energy Storage Units

Aggregated Energy Interaction and Marketing for the Demand Side with Hybrid Energy Storage Units

An aggregated energy interaction and marketing strategy is developed for demand side energy communities (DSECs) with hybrid energy storage units, considering the grid friendly issue. The whole mechanism is built as a hierarchical scheme. On the upper-layer, an aggregator is responsible for managing all demand responses through a game based energy scheduling and marketing strategy. On the lower-layer, each user-level energy prosumer (EP) pursues its optimal energy economical goal by participating in aggregated energy interactions within the DSEC through the energy router. Aiming for coordinated operation with the main grid, both energy self-equilibrium and grid friendliness criteria are incorporated with the hierarchical energy interaction and marketing model. The double-layered nonlinear system model is then converted into one single-layer mixed integer linear programming model and solved by the Tabu search-Particle swarm optimization algorithm. Case studies show that with the presented energy scheduling and marketing strategy, energy costs on the end user side are significantly reduced. In the case studies, the energy cost of the three EPs decreased by 3, 8 and 3% respectively. When grid friendliness was taken into account, the DSECA’ revenue was 28% higher than before and the load rate rise from 36.46 to 48.15%.
