Abstract

The invention relates to the technical field of electricity side bidding optimization, in particular to a bidding optimization method considering cross-region consumption of renewable energy sources.The method comprises the following steps of 1, building cost models of a non-renewable energy resource power station and a renewable energy resource power station in cross-region consumption; 2, building quotation models of the non-renewable energy resource power station and the renewable energy resource power station in cross-region consumption; 3, building income models of day-ahead markets of the non-renewable energy resource power station and the renewable energy resource power station in cross-region consumption; 4, building income models of intra-day markets of the non-renewable energy resource power station and the renewable energy resource power station in cross-region consumption; 5, judging whether ultra-high-voltage line supply and demand meet an ultra-high-voltage line supply and demand balance constraint condition or not; and 6, solving a balance problem with a balance constraint. According to a simulation result, the incomes are maximized by changing corresponding quotation parameters; the consumption level of the renewable energy source power station is improved through the ultra-high-voltage line; and both the non-renewable energy resource power station and the renewable energy resource power station achieve relatively high incomes.

Description

technical field [0001] The invention relates to the technical field of electricity-side bidding optimization, and relates to a bidding optimization method that takes into account the cross-regional consumption of renewable energy. Background technique [0002] In recent years, my country's renewable energy has developed rapidly and achieved world-renowned development achievements, but at the same time, the "three wastes" of renewable energy "abandoning wind", "abandoning light" and "abandoning water" are also continuously deteriorating. In the case of limited local consumption capacity of renewable energy, cross-regional consumption can effectively utilize the complementarity between multi-regional electricity load and renewable energy output, and significantly improve the overall renewable energy consumption capacity. Due to the volatility and randomness of renewable energy generation such as wind power and photovoltaic power generation, simply sending renewable energy will...
