中文摘要:
      基于电力市场的竞价机制和虚拟电厂的运行机制,本文首先构建了以风电-光伏-负荷-储能联合运行体利润最大化为目标的优化决策模型。该模型充分考虑新能源机组,储能与负荷运行时的各项技术约束条件,通过虚拟电厂中风-光-荷-储间协调耦合运行的发电策略与出力安排等,来实现新能源与电动汽车联合参与市场竞价。在此基础上,构建算例验证所提出的风光储联合运行优化决策模型的正确性与有效性,并通过对多组场景对比,分析新能源出力波动性对风-光-荷-储联合运行模式的竞价策略的影响。
英文摘要:
      According to the bidding mechanism in electricity market and operating principles of , this paper constructs a profit-maximization optimized decision model under the environment of electric power market with the joint wind, solar units, loads and energy storage systems. The model fully considers various technical constraints of renewables units and storages, realizes the participation of new energy and electric vehicle in the market bidding through power generation strategy and the output arrangement of the coordinated operation of the virtual power plant. On this basis, numerical examples are implemented to validate the correctness and validity of the optimal decision-making model of joint wind, solar units, loads and energy storage systems. Furthermore, the influences of the output fluctuations of renewable energies on the bidding strategies of the joint system are compared by the multi-operating scenarios.
