Abstract

The invention discloses a production simulation model for power generation. The production simulation model for power generation comprises an operation simulation basic procedure sub-model, a model description sub-model, a calculating module, a process sub-model, a unit combination sub-model, an economic dispatch sub-model and an auxiliary problem processing sub-model.

Description

technical field [0001] The invention relates to the technical field of electric power saving, in particular to a power generation production simulation model. Background technique [0002] Power system operation simulation can be summarized into two types: deterministic model and uncertain model. Under the time-series load curve, the deterministic model first arranges the positions of non-thermal power units in the load according to the type of units, and then allocates the economic output of thermal power units. Uncertain models can be divided into random and probabilistic. The stochastic uncertain model is to perform production simulation calculation directly under the time series load curve, the main methods are: Monte Carlo and Markov method; the probabilistic model is to perform production simulation calculation under the equivalent load continuous curve, the main method is segmented straight line approximation method, block method, equivalent electric quantity functi...

Problems solved by technology

For deterministic and uncertain production simulations, each has its own advantages and disadvantages: deterministic production simulation can consider some constraints related to time and space, such as unit start-up and shutdown, peak shaving problems, grid constraints, etc., but deterministic models only Using a certain reserve capacity of the system to simulate unit accidents lacks depth in the reliability analysis of the power system; the uncertain production simulation makes up for the deficiencies of the deterministic simulation, but has the following disadvantages: the production simulation is performed under the time-series load curve The calculation loses its adaptability due to the large amount of calculation, and the simulation based on the equivalent load continuation curve lacks consideration of the peak shaving status of the system, etc.

[0004] In the process of realizing the present invention, the inventor found that there are at least defects such as large amount of calculation, small application range and poor simulation effect in the prior art
