摘要
随着园区综合能源系统的不断发展与普及,其与上级大电网并网实现交互已成为大势所趋.文中构建了通过联络线相耦合的多园区综合能源系统接入主动配电网的双层优化调度模型.在主动配电网层面,以最小运行成本为目标,充分考虑了联络线功率、分布式电源、储能设备、柔性负荷、电动汽车等可调度资源;在园区层面,以多园区总运行成本最小为目标,考虑了相互联结的多类型园区的并网情况.利用目标级联法对双层模型进行求解.通过算例验证,文中所构建模型具有良好的经济特性与削峰填谷效果,充分证明了文中所提模型的经济性与有效性.
Abstract
With the continuous development and popularization of the park-level integrated energy system,it has become a general trend to connect it to the superior power grid and realize the interaction.In this paper,a two-layer optimization model of connecting multi-park integrated energy system to active distribution network is constructed.At the level of active distribution network,schedulable resources such as link-line power,distributed generation,energy storage equipment,flexible load and electric vehicles are taken into full consideration with the goal of minimum operation cost.At the park level,aiming at minimum total operation cost,the grid-connection situation of multi-type parks connected with each other is considered.Analytical target cascading is used to solve the two-layer model.Through the calculation examples,the proposed model has good economic characteristics and peak cutting and valley filling effect,which fully proves the economy and effectiveness of the proposed model.
