Photovoltaic access capacity optimization algorithm of wind-photovoltaic combination farm project

Abstract

The invention discloses a photovoltaic access capacity optimization algorithm of a wind-photovoltaic combination farm project. The algorithm comprises the following steps of determining the main transformer capacity of a wind farm booster station, calculating an average output time sequence peak of a wind farm in a setting time period, wherein the difference of the main transformer capacity and the average output time sequence peak can be a key basis of the photovoltaic capacity. The method can adopt the reserve capacity of the in-use equipment of the wind farm booster station in a maximizing way, the best configuration capacity of the photovoltaic capacity is reckoned as an optimization object, a wind-photovoltaic combination power station with best economic benefit can be built based on the operating data samples of wind farm in prior art, and the contingent probability theory is used as a guiding ideology. According to the invention, the configurable photovoltaic capacity of the wind farm under a preset condition can be precisely calculated, and the algorithm has a guiding function in detail for the optimizing configuration of the wind farm and the capacity upgrade.

Description

technical field [0001] The present invention relates to the field of wind and solar power generation, in particular to an optimization algorithm for photovoltaic access capacity of a wind and solar project. Background technique [0002] In recent years, the contradictions between economic development, energy supply and environmental pollution have been intensified. In order to realize the sustainable development of energy and economy, the governments of various countries, especially European and American countries, have put their own new energy development issues into consideration from the perspective of strategic significance. Wind power and photovoltaic power generation are currently the most widely used, most mature technology, and best commercialized forms of new energy utilization in China. However, wind power and photovoltaics are energy sources with low density, strong randomness, and poor stability. The construction of wind power and photovoltaic projects also brin...
