Abstract

The invention relates to a wind power optimal planning modeling method considering the adaptability and economy of a power system. The method comprises following steps: acquiring basic information of the power system; establishing a calculation model; setting the installed capacity, installed areas, power transmission line load rate upper limits of a wind power plant; selecting wind curtailment cost coefficients according to the deflection degree of an object; and working out the model. The power generation cost, power transmission investment and wind curtailment cost of the power system are considered in an objective function, and factors such as system peak regulation and power transmission capacity are also taken into account, so that wind power integration consumption and system investment operation economy of the planning model can reach the equilibrium. Through the solution of the model, the economy and adaptability of a wind power planning scheme can be multi-dimensionally evaluated, and a reasonable wind power construction area, a reasonable wind power construction scale, and an optimal construction scheme and an optimal time sequence for power transmission lines can be obtained, so that decision bases can be provided for wind power planners.

Description

Technical field: [0001] The invention relates to a modeling method for wind power optimization planning, and more specifically relates to a wind power optimization planning modeling method considering power system adaptability and economy. Background technique: [0002] With the vigorous development of wind power, the uncertainty and randomness of its output have brought new challenges to the operation and planning of the power system. In terms of grid transmission capacity requirements, especially the relatively weak grid foundation often makes it difficult to accommodate wind power on a large scale. Therefore, wind power planning must be compatible with the power grid and power supply, that is, large-scale wind power grid connection must match the peak-shaving capability of the power supply, without damaging the safe and stable operation of the system, and at the same time match the transmission capacity of the power grid, regardless of the location of the wind farm. And ...
