A production simulation method for power system with source-grid-load-storage coordination

Abstract

The invention provides a method for simulating the production of a source-network-load-storage coordinated power system, including establishing a generation-side unit scheduling cost model, a load-demand side resource scheduling cost model, and a system carbon emission cost model; The goal is to minimize the total cost, and an optimization model including objective functions and constraints is established; according to the optimization model, various time points and regions in the production simulation cycle are obtained: various power generation power, demand response load reduction power, and demand response load transfer-out power , demand response load transfer power and energy storage charging and discharging power, and the transmission power of each cross-regional transmission channel at each time point in the production simulation cycle. The invention solves the mathematical model to obtain the optimized operation mode of the power supply, the power grid, the load side resources and the energy storage, and ensures the coordination of the scheduling modes of various resources, so as to realize the overall optimization of the system.

Description

technical field [0001] The invention relates to the technical field of power supply systems, in particular to a method for simulating production of a source-network-load-storage coordinated power system. Background technique [0002] Power system production simulation is a technical means to verify the feasibility of power planning schemes and analyze the operating characteristics of power systems under different development states. After the power planning is carried out, the system operation state simulation is carried out based on a certain planning scheme, the main indicators of the power system operation under the corresponding planning scheme are obtained, the rationality of the planning scheme is analyzed, and key indicators (such as wind curtailment rate, solar curtailment rate, etc.) are studied ) of the influencing factors. According to the conventional cognitive framework, the power system consists of three parts: the generation side, the grid side, and the load ...

AI Technical Summary

Problems solved by technology

[0004] The main deficiency of the existing power system production simulation technology is: the overall optimization simulation of power supply, power grid, load-side resources, and energy storage has not been realized

However, there is no production simulation method that coordinates and considers various resources on the power supply side, grid side, load side, and energy storage side of the power system and solves them in a unified manner.
