可再生能源的整合、消费者的积极作用和能源管理系统目前是能源系统的研究重点之一。针对具有不同消费模式的邻域消费者组成的微电网，提出了一种创新的协调能源调度方法。所有的消费者都有光伏发电系统，锂离子电池作为储能系统，以及常规的家庭负载。采用遗传算法对每个用户的电池充放电进行调度，目标是通过最小化微电网与主电网互联点的功率来减少能量交换损失，与经典的优化目标相比具有几个优点，并且不会恶化电池寿命的退化。对个体策略和协调策略进行了比较，并对消费者集合的自我消费和自给自足进行了评价，目的是展示协调的优势。本文的结论是，协调运行有助于提高用电微网的能源利用率，减少与配电网交换的能量约13%，同时避免增加电池循环和随之而来的退化。
Integration of renewable energy sources, active role of consumers, and energy management systems is currently among research priorities in energy systems. This paper proposes an innovative coordinated energy scheduling for a microgrid of neighbor prosumers with different consumption patterns. All prosumers have photovoltaic generation systems, Li-ion batteries as energy storage systems, and regular household loads. A genetic algorithm is used to schedule each prosumer's battery charge/discharge, with the aim of reducing energy exchange losses by minimizing the power in the point of interconnection of the microgrid with the main grid, with several advantages compared to classical optimization objectives, and without worsening battery lifespan degradation. Individual and coordinated strategies are compared, and self-consumption and self-sufficiency of the prosumers’ set are evaluated with the aim of showing the advantage of coordination. The paper concludes that coordinated operation can contribute to improve the exploitation of energy resources in the prosumer microgrid, reducing the amount of energy interchanged with the distribution grid by approximately 13%, and, at the same time, avoiding increasing the battery cycling and consequent degradation.
