| 摘要: |
| 综合能源系统实现了冷、热、电等多种能源形式的横向互补以及“源-网-荷-储”多个环节的纵向协调。基于区域综合能源系统功能区内冷热产消就地平衡，以及电作为功能区间能量枢纽的特点，分析了典型功能区“源-网-荷-储”的差异特性，包括电动汽车(EV)的时空特征、用户冷热需求的柔性和供热系统的热惯性等；考虑了EV负荷、冷热负荷和供热系统的虚拟储能特性，建立了计及功能区间能量交换能力、储能设备成本等差异的区域综合能源系统实体储能(设备)规划模型；以某一包含居民区、办公区、商业区和工业区的新区综合能源系统为例进行算例分析，结果表明考虑了虚拟储能的多功能区综合能源系统优化调度为整个系统带来了更多的弹性和联网效益，有效减少了消纳可再生能源所需的实体储能配置容量。 |

| Abstract: |
| Integrated energy system positively contributes to the horizontal complementation of various energy forms including cooling, heating and power etc.,and multiple vertical coordination among “sources, grid, demands and storages”. The cooling and thermal production and consumption are balanced within each functional area, and the power system is operated as an energy hub. Based on this, the difference characte-ristics of “sources, grid, demands and storages” in typical functional areas are analyzed, including the spatial-temporal characteristics of EV(Electric Vehicle),the flexibility of cooling and heating loads, and the thermal inertia of a heating supply network. Then, the virtual storage characteristics of EV, cooling and heating loads and heating supply network are exploited. Moreover, a physical storage(equipment) planning model of a regional integrated energy system is developed, which considers the differences of energy exchange capacities and the storage equipment costs in the functional areas. Numerical results of an integrated energy system represented by a new district including residential, office, commercial and industrial subareas demonstrate that the optimal scheduling of integrated energy system with multiple functional areas considering virtual storage can improve the elasticity of whole system and networking benefit, and it can effectively reduce the physical storage capacity required to accommodate renewable energy. |
