The swift evolution of advanced power systems has resulted in a substantial rise in the share of renewable energy sources within these networks, which poses a challenge to the system's scheduling capabilities due to its inherent instability. In order to meet the demands for flexibility and to facilitate harmonious interaction among the diverse elements within the power system, this paper proposes an optimized configuration model for the power system based on the supply-demand relationship and coordinated operation among the power generators in source-load-storage sides. The model combines the operation flexibility of power supply and storage, as well as the overall flexibility. Constraints are imposed on the supply-demand relationship between the energy supply and load sides, and the output power of source sides and storage stations on the power supply and storage sides. An evaluation of the overall flexibility is conducted. This advanced scheduling model is designed to optimize by reducing the overall operational cost, achieving this goal through the definition of a specific objective function.. To address the nonlinear components in cost calculations, a quadratic function is segmented and linearized, and the CPLEX solver in MATLAB 2022a is utilized to obtain the optimal solution. Through case studies with three distinct scenarios, the viability and efficacy of the proposed model have been substantiated, demonstrating improved renewable energy consumption, reduced wind power curtailment, and made the load curve more stable.
