| Abstract: |
| In order to promote the power grid and terminal DIES(Distributed Integrated Energy System) to share the responsibility of the users’ energy supply reliability by market mechanism, and fully reflect the reliability value of DIES, an optimal configuration method of integrated energy system equipment considering reliability value is proposed. Based on the electricity price of node considering reliability and the reliability evaluation of DIES, a grid-connected electricity price estimation model considering reliability for DIES is constructed. Based on this, a two-layer collaborative planning model that takes into account optimal configuration and operation of equipment is established. The equipment capacity allocation with the goal of optimizing the total revenue of DIES is performed in the upper layer. Considering incremental value of reliability, the output of each unit is optimized with the goal of maximizing operating revenue in the lower layer. An example is used to verify the effectiveness of the optimal configuration model of integrated energy system considering reliability value, and the impacts of users’ load characteristics, users’ energy supply reliability requirements, and annual load growth rate of distribution network on the configuration results are analyzed. |
