Analysis of multi-scenario power supply and demand balance in Shandong power grid based on the new generation PSDB platform

Based on the new generation of PSDB platform, this paper proposes the power supply configuration scheme of Shandong power grid, which is used for the simulation calculation of power supply and demand balance production in Shandong power grid. The five power supply configuration schemes proposed in this paper, the power supply of scheme 1 (basic scheme) only considers projects that have been completed, are under construction, have been approved and have relatively clear plans; Scheme 2 to Scheme 5 are all based on the power supply configuration scheme of Scheme 1 to configure a guaranteed power supply to ensure the power supply of Shandong Power Grid. The simulation results of the power configuration of Scheme 3 to Scheme 5 show that the increase of the scale of new energy or the flexibility transformation of coal power basically does not affect the power balance at the moment when the Shandong grid gap is the largest, but it can improve the power supply at other times.
