Abstract

The invention discloses a data processing method and device for economic dispatch of a wind power plant. Mechanical constraint of thermal power generating units can be considered reasonably, and an optimization result can be obtained quickly and accurately by arranging an embargo area. The method comprises the steps of acquiring the number of thermal power generating units participating in economic dispatch, dispatch cycle, forecasting load of each time frame in the dispatch cycle, spinning reserve load of each time frame in the dispatch cycle, and the embargo area of the thermal power generating units, and establishing the constraint condition of actual operation; acquiring the parameters of each thermal power generating unit, and establishing an objective function; systemizing the objective function and the constraint condition to obtain a generating cost minimization mathematical model; determining the initial value of unit output based on the principle that the unit with minimum average generating cost conducts outputting completely as priority; solving the generating cost minimization mathematical model according to the initial value of unit output, and making an economic dispatch optimizing scheme according to the solution.

Description

technical field [0001] The invention relates to the field of power system optimization, in particular to a data processing method and device for economic dispatch of wind farms. Background technique [0002] In the field of power system research, the research on economic dispatch of wind farms has always been a hot and difficult point. The power system economic dispatch optimization problem aims to minimize the total operating cost of the power system within the power system dispatch period, under the premise of satisfying various actual operating constraints, and determine the output of each thermal power unit in the system by rationally arranging The optimal unit output scheme. Studying the optimization of economic dispatch of wind farms can structurally optimize coal resources, make reasonable use of wind power as a renewable energy source, and reduce the harm caused by wind power grid integration, which is beneficial to the implementation of energy-saving and emission-r...
