Abstract

The invention relates to a low-carbon intelligent park resource-load coordination optimization method, and the method comprises the steps: initializing time t as zero, and enabling the time t to serve as the start point; initializing parameters of all time periods, and inputting state data; calculating the total carbon emission of a conventional set in the time period, the carbon emission limit of this time period and the carbon excessive emission cost; calculating the power generation cost of the conventional set and the generalized cost of wind power, and obtaining resource-load coordination call cost; determining a target function and a constraint condition, and consuming large-scale wind power through adjusting the output of a thermal power generating unit. The method solves a problem of resource-load coordination optimization of a low-carbon power system with a wind farm, finds an optimal solution to an optimization model, and achieves the system safety, economic and low-carbon targets.

Description

Technical field: [0001] The invention relates to the field of optimal dispatching, in particular to a method for coordinating and optimizing source and load in a low-carbon intelligent park. Background technique: [0002] The source-load coordination of low-carbon smart parks is very different from traditional optimization problems. Compared with the traditional optimization, it mainly studies the theoretical model and solution algorithm for improving the wind power accommodation capacity and operation economy after large-scale wind power is connected to the grid from different angles, but does not consider the mutual consumption of the callable load and the generator set Wind power only considers the optimal scheduling strategy from the power generation side, and fails to incorporate demand-side resources and low-carbon environmental protection indicators into the wind power scheduling system, making it difficult to meet the requirements of new energy consumption and carbon...
