To address the volatility and multitimescale uncertainty of renewable energy, this paper proposes an optimal configuration method of electric-thermal hybrid energy storage for DGW-NEB considering retrofitted coalfired power plants. The basic principle and internal energy flow relationship of retrofitted coalfired power plants are analysed, and a mathematical model is established. A two-stage optimization framework is established: the first stage generates candidate schemes by minimizing daily cost and curtailment rate under typical scenarios; the second stage carries out an 8760h time-series production simulation to select the optimal scheme targeting minimum annual equivalent cost and annual curtailment rate. The effectiveness of the proposed method is verified through a case study of a large-scale new energy base in the Kubuqi Desert, China.
The method provides practical references for the planning and construction of DGW-NEB.
