Scheduling evaluation method of intermittent energy power station and distribution method of power rationing for this evaluation

Abstract

The invention discloses a scheduling evaluation method for an intermittent energy power station, which includes the following steps: step 1, selecting an evaluation index for the intermittent energy power station; the selected grid-connected performance evaluation index is divided into three dimensions: electric energy prediction index, power station Operational technical level indicators and grid-connected level indicators of power stations; step 2, use the moment estimation optimization algorithm to calculate and distribute the weights of the above three latitude evaluation indicators; step 3, according to the weight distribution in step 2, establish intermittent energy power station dispatching indicators Evaluation model, evaluation and scoring; through the establishment of a new energy grid-connected scheduling sequence evaluation model, supplemented by moment estimation optimization algorithm to assign weights, realize the ranking of the grid-connected performance of each power station, and based on this, rationally allocate the power rationing of each new energy power station capacity share. It has a positive guiding role in improving the operation technology level of intermittent energy power stations.

Description

technical field [0001] The invention relates to the technical field of short-term dispatching of electric power system grids, in particular to an evaluation method for dispatching of intermittent energy power stations and a power-limiting distribution method for the evaluation. Background technique [0002] With the increasing proportion of intermittent energy in the grid, intermittent energy has become one of the main power sources of the grid. However, as a new type of power source, the technology level of intermittent energy is not yet mature, and the management mode has not been fully determined, resulting in uneven technical and operational levels of intermittent energy power stations, which has brought many difficulties to the operation of power grid dispatching agencies. In order to better ensure the power balance of the power grid, intermittent energy must be included in the management of the grid dispatching plan. The power prediction of intermittent energy at the d...
