中文摘要:

针对分布式能源的聚合调度及消纳问题，提出了一种虚拟电厂调度优化方法。文中考虑电力损耗、电压支持和线路拥塞等约束条件，以利润在最大化为目标，基于随机混合整数线性规划对系统中机组组合和可控负载调度进行优化，将虚拟电厂的概念用于研究不同分布式能源的技术和经济影响，将分布式能源对系统效益的贡献进行量化，利用合作博弈论中的分配机制，以公平高效方式进行效益分配。此外，在不同运行策略下，分析了电动汽车和商用暖通空调系统对系统灵活性的影响，以及电动汽车作为移动储能系统在可再生能源发电量突降时辅助电网运行的可行性，在测试系统上进行了案例研究。结果表明，电动汽车对虚拟电厂的边际贡献最大，太阳能发电紧随其后。结果还显示，所提出的方法提高了系统经济收益，同时改善了多项技术运行指标，验证了所提出方法的有效性。

英文摘要:

Aiming at the problem of aggregated scheduling and consumption of distributed energy resources, the paper proposes a virtual power plant scheduling optimization method. Considering constraints such as power loss, voltage support and line congestion, the combination of units and controllable load scheduling in the system is optimized based on stochastic mixed integer linear programming with the objective of profit-in-maximization. The concept of virtual power plant is applied to study the technical and economic impacts of different distributed energy sources. The contribution of distributed energy sources to the system benefits is quantified, and the distribution mechanism in cooperative game theory is utilized to distribute the benefits in a fair and efficient manner. In addition, the impact of electric vehicles (EVs) and commercial heating-ventilation-air conditioning (HVAC) systems on system flexibility is analyzed under different operating strategies, as well as the feasibility of EVs as mobile energy storage systems to assist power grid operation during sudden drops in renewable energy generation. A case study is conducted on a test system. The results show that EVs have the highest marginal contribution to the virtual power plant, followed closely by solar power generation. The results also show that the proposed methodology improves the economic return of the system, as well as a number of technical operational indicators, validating the effectiveness of the proposed methodology.
