Security constraint generation schedule planning method based on water and fire coordination

Abstract

The invention provides a security constraint generation schedule planning method based on water and fire coordination. The method comprises the following steps that power grid basic data are acquired, and electricity demands are determined; based on 'just, fair and open' dispatching and energy-saving dispatching, the electric quantity is balanced, and electric power is adjusted; according to the water and fire coordination constraint demand, the constraint condition of a water and fire coordination joint optimization model is determined; an optimization objective is determined; water and fire coordination joint optimization computing is carried out, and the generation schedule is determined. According to the method, based on the running and planning characteristic of a power grid including a large-scale water and electricity access dispatching mechanism, the water and electricity running and water and fire coordination optimizing characteristics are combined, the optimization objective includes the running cost of a thermal power unit and a hydropower unit and a unit output force adjusting penalty function, peak elimination and valley filling are carried out through coordination of the hydropower unit and the thermal power unit, so that the total adjusting amplitude of output force of the units in the system is reduced, and therefore power adjustment losses of the units in the system are reduced.

Description

technical field [0001] The invention relates to a method in the field of power grid dispatching including large-scale hydropower access, in particular to a safety-constrained power generation plan formulation method based on water-fire coordination. Background technique [0002] With the rapid development of the economy, the contradiction between energy and the environment is becoming increasingly severe. How to improve energy utilization efficiency, save energy consumption, and reduce environmental pollution is an important issue we are currently facing. One of the main means to solve this problem is to increase the proportion of clean energy and the ability of the grid to absorb it. The main types of clean energy are hydropower, wind power, and photovoltaic power generation. Compared with other clean energy, hydropower has obvious advantages such as low cost, flexible adjustment, and abundant reserves, and has become an important part of the energy structure of the power s...

Problems solved by technology

However, under the "three public" dispatching and energy-saving dispatching modes, there is no power purchase cost curve, and other methods need to be selected to drive water and fire coordination and optimal dispatching
