A combined decision-making method for multi-type power generation plan

Abstract

Disclosed are a combined decision method for power generation plans of multiple power sources, and a storage medium. The multiple power sources comprise a power generation system composed of thermal power, wind power and pumped storage. The combined decision method is: according to power grid requirement information, combined with a power balance analysis result, preferably choosing a starting and stopping state of a thermal power set; establishing an optimization model in which the multiple power sources are coordinated, and carrying out joint optimization for active power outputting of a wind power-thermal power-pumped storage set; and implementing a security check on an active power outputting plan of the multiple power sources, iteratively correcting a starting and stopping plan of the thermal power set, and finally, generating a combined power generation plan of the multiple power sources. The present solution brings wind power prediction data into power balance and arranges the starting and stopping of a thermal power set in advance, so that the effect of peak clipping and valley filling of a pumped storage set can be achieved, and a joint decision of power generation plans of multiple power sources, such as thermal power, wind power and pumped storage, can be realized so as to replace or reduce the power generation capacity of a thermal power set, and thus the consumption and absorption level for clean energy of a power grid can be improved.

Description

technical field [0001] The invention belongs to the technical field of electric power system scheduling automation, and in particular relates to a method for combining decision-making of multi-type power generation plans. Background technique [0002] With the grid-connected power generation of large-scale clean energy represented by wind power and photovoltaic power generation, the characteristics of clean energy such as volatility and anti-peak regulation make it difficult to adjust the frequency and peak regulation of the power grid, and the resulting problem of clean energy consumption has become a problem. Bottlenecks restricting the large-scale utilization of clean energy power generation in China. An important measure to solve this problem is to use energy storage equipment to store the electric energy during the wind power generation period and use it during the peak load period, so as to maximize the benefits of wind power. [0003] Pumped storage is currently the ...

Domestic power generation dispatching must not only implement the implementation of energy-saving power generation dispatching methods, ensure the priority dispatching of wind power, but also ensure the effective implementation of power contracts of power plants. The problem of unit combination in this environment has high computational complexity. Results are hard to quantify

The problem of multi-power combination includes the combination of thermal power units, the progress of electricity contract completion, the priority consumption of wind power, the coordinated operation of wind power-thermal power-pumped storage, and grid security. From a mathematical point of view, it is difficult to establish a unified optimization model to solve the problem of multi-power combination
