Research on two-layer Optimal Dispatching of multi-park Integrated Energy System connected to Active Distribution Network
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.
