微电网允许在多个相互连接的微电网之间进行能源交换，以提高能源效率和集体经济利益。然而，在某些情况下，电网内某些微电网的效益可能并非不确定。针对电动汽车的日益发展，提出了一种基于全局和个体利益平衡的多目标模型，通过整合电动汽车到电网（V2G）和汽车到建筑（V2B）来提高微电网的性能。为了验证该方法的有效性，建立了两个参考模型，并将模型表示为混合整数线性规划格式，采用加权法求解。采用一组微电网参数，对上海五座商业建筑（如酒店）的驾驶员行为（如电动汽车可用小时数）、能源交易（如电力）、性能因素（如排放因素）、分布式能源（如太阳能电池板）和能源负荷进行建模。仿真结果验证了该模型在中性、亲经济、亲环境和亲能源加权场景下微电网能量管理中的有效性。案例研究结果表明，该方法可以实现每个微电网的运营成本、二氧化碳排放和一次能源消耗的降低，但总效益略有下降。
Microgrids allow energy exchange among multiple interconnected microgrids for greater energy efficiency and collective economic interest. However, in some cases, the benefit of some microgrids within the network may not be uncertain. In view of the increasing development of electric vehicles (EVs), a multiobjective model is proposed to improve the performance of microgrids by integrating electric vehicles-to-grid (V2G) and vehicles-to-building (V2B) based on global and individual benefit balance. Two reference models are built to verify the validity of the proposed method, and models are formulated as mixed integer linear programming formats solved by the weighting method. A set of parameters of microgrids are adopted to model the driver behaviors (e.g., available hours of EV), energy transactions (e.g., electricity), performance factor (e.g., emission factor), distributed energy (e.g., solar panel), and energy load of five commercial buildings (e.g., hotel) located in Shanghai. Simulation results demonstrate the effectiveness of the operation decision models in the energy management of microgrids under neutral, proeconomic, proenvironmental, and proenergy weighting scenarios. The case study results specify that the proposed method can achieve operational cost, CO2 emission, and primary energy consumption reductions for each microgrid, with total benefits declining slightly.
