Problems solved by technology

However, this algorithm also has obvious defects, mainly due to the non-convexity of the objective function, there is a dual gap in the solution process, and often the optimal solution of the original problem cannot be found, and certain measures need to be taken to construct

Abstract

The invention relates to a generator unit start-stop configuration method and system based on a depth deterministic policy algorithm. The method constructs a unit commitment start-stop allocation problem into an enhanced learning sequence decision problem. The method comprises the steps that 1) the output value vector of each unit at a previous historical moment is used as an intelligent body observation state and the input vector of a depth policy network; and 2) for a continuous time sequence unit start-stop optimization problem, the depth deterministic policy gradient algorithm is used to provide an optimization decision sequence and output the start-stop vector of the unit at the moment to realize the allocation of the start-stop status of the unit. Compared with the prior art, the method and system, which are provided by the invention, have the advantages that the depth deterministic policy learning method is used to directly acquire start-stop vectors at different moments; the method and system can adapt to the automatic allocation of the start-stop tables of unit clusters of different scales; and the system has better expandability.

Description

technical field [0001] The invention relates to the technical field of thermal power generation, in particular to a method and system for configuring start-stop of a generator set based on a deep deterministic strategy algorithm. Background technique [0002] In the production process of thermal power generation, it is of great significance to formulate a day-ahead power generation plan and optimize the configuration of the start-up and stop of the generating set in advance. The reason lies in two aspects: First, the power system load has obvious periodicity and peak-valley effects. In order to meet the demand of the load, the units in the system must operate jointly; secondly, without changing the number of start-up and shutdown units, only It is difficult to achieve the balance of power supply and demand and the rational allocation of power generation resources by adjusting the output of the starting unit. [0003] The optimal configuration of generator start-stop is how ...
