Source network load storage coordination power system production simulation method

Abstract

The invention provides a source network load storage coordination power system production simulation method. The method comprises the steps of: establishing a power generation side unit scheduling cost model, a load demand side resource scheduling cost model and a system carbon emission cost model; according to the models, taking the minimum total cost of the system in a production simulation period as a target to establish an optimization model comprising a target function and a constraint condition; and according to the optimization model, obtaining each time point and each area in the production simulation period: various power source generation power, demand response load reduction power, demand response load transfer-out power, demand response load transfer-in power and energy storagecharge-discharge power, and transmission channel transmission power in each cross-district at each time point in the production simulation period. The source network load storage coordination power system production simulation method employs the mathematical models to obtain an optimization operation mode of the power source, the power grid, the load side resource and the energy storage to ensurethe coordination of the scheduling modes of various resources and achieve the whole 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, 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 the key indicators (such as wind curtailment rate, solar curtailment rate, etc.) are studied. ) factors. According to the conventional cognitive framework, the power system consists of three parts: the generation side, the grid side, and the load side. In the past, power sys...

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.
