Embodiment Construction

[0070] Below in conjunction with accompanying drawing of description, the present invention will be further described.

[0071] Such as figure 1 As shown, the present invention provides a method for optimizing power generation based on a virtual power plant, comprising the following steps:

[0072] Step 1. Judging the level of comfort loss of the office building as a virtual power plant, specifically:

[0073] 1) Calculation of staff dissatisfaction indicators in office buildings

[0074] The dissatisfaction index of the staff in the office building is obtained through the formula (1);

[0075] PPD=100-95exp(-0.03353×PMV 4 -0.2179×PMV 2 ) (1)

[0076] Among them, PMV is the average thermal sensation index (Predicted Mean Vote), which is used to characterize the thermal response of the human body, and PPD is the index of personnel dissatisfaction in office buildings. , the relationship between PPD and PMV is as follows figure 1 As shown, PMV=0, that is, when the heating ...

Abstract

The invention discloses an optimized power generation method based on a virtual power plant. The method comprises the steps that the comfort loss level of an office building serving as the virtual power plant is judged; and power generation is optimized according to the comfort loss level of the office building. The office building comfort decline level is determined by calculating the subjective and objective indexes of the dissatisfaction degree of the staff in the office building and the working efficiency decline percentage, so that the power generation of the virtual power plant is optimized with the minimum cost and the maximum income under the condition that the office building comfort is further ensured, and the optimal power generation effect is achieved under the condition of ensuring personnel comfort as much as possible.

Description

technical field [0001] The invention belongs to the technical field of power generation, and in particular relates to an optimized power generation method and system based on a virtual power plant. Background technique [0002] In recent years, the power load characteristics of super-large cities have deteriorated, the load growth rate is higher than the power growth rate, the peak-to-valley difference has increased, and the peak-shaving difficulty of the system in summer has become prominent. With the implementation of virtual power plants in China, super-large cities rely on their huge office building load resources to build virtual power plants to alleviate problems such as peak regulation of the power system. The office building load dominated by central air conditioning is the main reason for the peak load of the system. Based on the comfort requirements of the air-conditioning hot and humid environment, the power consumption of such loads has a certain adjustable space...
