Design and Simulation of Grid Connection Mechanism for Future Smart Grid Users Based on Virtual Power Plant Technology

未来智能电网用户不仅能够消费电能,还可以通过分布式能源并网出售电能。针对基于实时电价机制的未来智能电网,结合虚拟电厂技术,设计用户并网供电规则。考虑用户的多种博弈行为设计研究竞标策略,参考商业型和技术型虚拟电厂设计优化目标,建立了未来智能电网用户并网多目标优化模型。通过多起始点变邻域下降法与局部搜索相结合的优化算法,采用IEEE 118节点标准测试系统模拟区域电网进行仿真。数值仿真的计算结果验证了模型及算法的有效性。

In the future,smart grid users can not only consume energy,but also sell energy to the grid through distributed energy resources.The real-time pricing mechanism based future smart grid is proposed as the background of the research.Rules are designed for users to supply and merge energy by referring to real-time pricing and virtual power plant technology.Considering the variety of users'game behavior,bidding tactics are designed and studied.And by referring to the optimization objectives of commercial and technical virtual power plants,a future smart grid users'grid connection model for multiobjective optimization is developed.In addition,through the multi-start variable neighborhood descent method and local search algorithm,a IEEE 118-bus standard test system is used to simulate a regional grid.The calculation results of numerical simulation have verified the effectiveness of the model and algorithm.
