用户侧多能互补微能源网的规划方法

多能互补的微能源网是一种可以提高能源利用效率的有效方式，并且可以通过整合多能源载体降低供电成本。面对多种多样的能量转换器和特性各异的储能设备，如何选择设备的类型和容量、如何连接和管理所选设备，是设计新型微能源网最优规划配置的核心问题。提出了一种面向用户侧多能互补微能源网的规划方法，充分发挥多能互补的优势，得出了最优规划配置。将最优规划问题转化为一个混合整数线性规划模型，目的是使得总成本最小。算例结合北京市海淀区某能源互联网示范工程，对3种不同的能源系统方案进行了比较，验证所提出的最优规划模型的有效性和优越性。

Planning Method of Multi-energy Complementary Micro Energy Grid on User Side

Multi-energy complementary micro-energy grid is an effective way to improve energy efficiency and reduce power supply costs through integrating multi-energy carriers.Against numerous energy converters of various types and storage devices with different characteristics, the selection of the type and capacity of the devices, and the connection and management of the selected devices are the key challenging problems for designing the optimal configurations of new micro energy grids. This paper proposes a new planning method of multi-energy complementary micro energy grid on user side, which can give full play to the advantages of multi-energy complementary and obtain the optimal configuration. The optimal planning model is a mixed-integer linear programming with the objective to minimize the overall cost. The effectiveness and superiority of the optimal planning model proposed in this paper are demonstrated by comparing three different energy system schemes with an energy interconnection demonstration project in Haidian District of Beijing.
