Embodiment

[0082] see figure 1 , the present invention provides a technical solution:

[0083] The dispatch evaluation method of intermittent energy power station is characterized in that it comprises the following steps:

[0084] Step 1. Select the evaluation indicators for intermittent energy power plants; the selected grid-connected performance evaluation indicators are divided into three dimensions: electric energy prediction indicators, power station operation technical level indicators, and power station grid-connected level indicators;

[0085] Step 2, use the moment estimation optimization algorithm to calculate and distribute the weights of the above three latitude evaluation indicators;

[0086] Step 3, according to the weight distribution in step 2, establish an evaluation model for dispatching indicators of intermittent energy power plants, and perform evaluation and scoring;

[0087] Assuming that the grid-connected performance index information of intermittent energy powe...

Abstract

The invention discloses an intermittent power station dispatching evaluation method, which comprises the following steps: 1, evaluation indexes for the intermittent power station are selected, whereinthe selected grid-connected performance evaluation indexes are divided to three dimensions: a power prediction index, a power station operation technical level index and a power station grid-connected level index; 2, a moment estimation optimization algorithm is used to perform weight calculation and distribution on the three dimensions of evaluation indexes; and 3, according to the weight distribution in the second step, an intermittent power station dispatching index evaluation model is built, and evaluation scoring is carried out; and through building a new energy grid-connected dispatching sequence evaluation model and with the help of the moment estimation optimization algorithm for weight distribution, the grid-connected performance of each power station is ranked, and on the basis,the power limiting capacity share of each new energy station can be distributed rationally. A positive guiding role is played to enhance the intermittent power station operation technical level.

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...
