Abstract

Provided is a smart-grid-orientated bidding power generation risk control method. The smart-grid-orientated bidding power generation risk control method comprises the steps that (1) real-time influence of bidding behaviors of generation companies on the market electricity price is taken into account from the perspective of the power generation side, and a novel power generation side market electricity price prediction real-time correction mechanism is built on the basis of the wavelet decomposition and reconstruction theory and the differential evolutionary support vector machine theory; (2) on the basis of a power generation side market electricity price prediction real-time correction module and a bidding risk quantitative evaluation module, a novel bidding risk feedback compensation dynamic self-adaptation control mechanism is built by using the feedback compensation control principle and the rapid PID incremental algorithm, stable and reliable dynamic self-adaptation control over the bidding risk is achieved, therefore, linkage optimization of the offered electricity price is driven along with unit output in the time periods of a trading day, and key risk control method support is provided for achievement of low-cost energy saving and emission reduction of the power generation side of a smart grid and low-risk and high-yield bidding grid entrance. The smart-grid-orientated bidding power generation risk control method is applicable to multi-target optimization bidding power generation of the power generation side in the smart grid environment.

Description

technical field

[0001] The invention relates to a smart grid-oriented bidding power generation risk control method, which belongs to the technical field of power generation economic operation. Background technique

[0002] The essence of the smart grid is to solve the problems of grid-connected renewable energy and rational utilization of energy through the informatization, intelligence, and marketization of power transmission and distribution networks and electrical equipment. The construction of smart grid with low-carbon and environmental protection as an important goal will profoundly affect the development model of the future power market. In addition to economic goals, the future power market should further consider energy conservation and emission reduction factors, that is, to the so-called "green power". market" development. In addition, the power structure in the smart grid will also undergo major adjustments. The large-scale access of renewable energy and its inh...
