Embodiment

[0143] Load and wind power forecast curves such as figure 1 As shown, the parameters of the unit are shown in Table 1, and the settings of other parameters are shown in Table 2. Here, the calculation period is one day, and one day is divided into 24 periods t, that is, Δt=1. In addition, in the example analysis, the basic peak-shaving method refers to the peak-shaving method in which the unit output value is kept within the output range of the unit, and the paid peak-shaving method refers to the deep peak-shaving or start-stop peak-shaving method of some units during peak-shaving.

Abstract

The invention provides a techno-economic evaluation method for a supply side involving in new energy peak regulation. The method comprises following steps of evaluating running cost and gains of a wind power plant side; evaluating running cost and gains of a thermal power plant; and determining a comprehensive benefit optimization model of the supply side. Wind power integration can have some impact on peak regulation technology output and economic benefit of a thermal power unit. Due to optimization of wind power acceptance volume and thermal power unit output, total economic benefit of the wind power side and the thermal power side is maximized; and policy support is provided for a peak regulation auxiliary service offered by the thermal power unit, so that the initiative involving in peak regulation of the thermal power unit is greatly improved.

Description

technical field [0001] The invention relates to an evaluation method, in particular to a technical and economic evaluation method in which the supply side participates in new energy peak regulation. Background technique [0002] Although the theoretical research in the field of technical and economic evaluation has been very mature, there are still few studies on the application of technical and economic evaluation theory to power system peak regulation. Techno-economic evaluation is mostly used in the implementation of projects. China has not yet established a set of effective peak shaving service evaluation index framework system to fully, scientifically and reasonably reflect whether the peak shaving scheduling arrangement is reasonable, whether the operation is normal, and resource optimization. Whether the configuration function is effective, etc. Moreover, different types of power supplies have different working characteristics during peak regulation, so it is difficu...
