Abstract

The present invention relates to a stochastic production simulation method and application of a sending-end power system considering energy abandonment constraints. The stochastic production simulation method includes the following steps: 1) Obtaining the annual load curve, and removing all nuclear power plants from the annual load curve. Annual output curve to obtain the continuous load curve, and according to the annual load level, the continuous load curve is divided into three stages: base load, waist load and peak load; 2) establish an equivalent power function according to the continuous load curve; 3 ) Realize output control of thermal power units and hydroelectric units at different stages according to equivalent electricity; 4) Consider the quotation of clean energy and its energy abandonment constraints, dynamically adjust the output status of clean energy and thermal power units, and obtain random production simulation data of the power system . Compared with the prior art, the present invention considers that the discardable power generation capacity of clean energy such as solar energy and wind power can be used as a conventional power source to participate in power system peak regulation, so as to ensure the minimum pollution of the system to the environment.

Description

Technical field

[0001] The present invention relates to the field of power system planning and operation control technology, in particular to a random production simulation method and application of a power system at the sending end considering energy abandonment constraints. Background

[0002] Power system stochastic production simulation is one of the basic analysis tools for power system planning and operation, which calculates the power generation capacity, system production cost and system reliability index of each power plant by optimizing the production and operation of the generator set, considering the uncertainty of unit failure and load. Traditionally, nuclear power units do not participate in grid peak regulation, not because of unit design, but because of the higher cost of nuclear fuel and the smaller proportion of nuclear power. With the development and construction of nuclear power, wind power and photovoltaic power generation, it will be difficult to meet the ne...
