Method for modifying and checking plan based on feasible output interval in frequency modulation market

Abstract

The invention discloses a method for modifying and checking a plan based on a feasible output interval in a frequency modulation market. The method comprises dynamic checking and static checking. The plan modification check is carried out under the condition that the power plant is allowed to start and stop in the static check, and the plan modification check is carried out in the current starting mode in the dynamic check. Under the condition of selecting the static checking mode, a corresponding frequency modulation index is obtained, all reasonable feasible processing intervals are calculated through a feasible output interval algorithm, and whether the scheduling modification plan falls into the feasible output interval is checked; under the condition that the dynamic checking mode is selected, corresponding frequency modulation index parameters are obtained, a feasible output interval in the current starting-up state is calculated through a feasible output interval algorithm, and whether the scheduling modification plan falls into the feasible output interval or not is checked. And finally, a dispatcher is informed of a modification plan checking result, so that the reasonability of scheduling the modification plan is improved, the difficulty of power plant output adjustment is reduced, and the economic benefit of the power plant in the frequency modulation market is improved.

Description

technical field [0001] The invention belongs to the field of power grid operation control, and in particular relates to a method for modifying planned values ​​of power plants in the frequency regulation market environment. Background technique [0002] With the continuous deepening of the supply-side reform of the power grid and the continuous advancement of the construction of the power market, the interaction between the power market system and the traditional OCS system is getting closer and closer. China Southern Power Grid has successively established a power spot market based on Guangdong, a peak-shaving market in Guangxi, and a Yunnan peak-shaving market. FM market etc. Among them, the frequency regulation market is an important part of the power market. Under the environment of the operation of the frequency regulation market, many demands are put forward for the OCS system. In the OCS system, especially the operation of dispatching human intervention, it is necessa...

Problems solved by technology

[0003] At present, when dispatchers revise the plan, they only modify the plan based on the dispatcher's grasp of the operation of the power grid and their own dispatching experience. In the frequency regulation market environment, if the dispatch modification plan is not checked, it is easy to cause the dispatch modification plan to be inconsistent with the frequency regulation market. Clearance conflicts, resulting in difficulties in clearing the frequency regulation market and difficulty in implementing plans for power plants
