Embodiment Construction

[0090] Refer below Figure 4-Figure 6 Describe in detail an embodiment of the peak shaving evaluation method based on distributed energy station access provided by the present invention; Figure 4 As shown, the implementation of a peak shaving evaluation process based on distributed energy station access in this embodiment mainly includes the following steps:

[0091] In the peak-shaving effect analysis step S1, set the start-up period and peak-shaving operation mode of the distributed energy station according to the preset daily power load data of the user area, and reduce the peak-valley difference according to the daily load curve of the user area. If the value is small, the power-on period and peak-shaving operation mode are dynamically adjusted.

[0092] In addition, considering that the distributed energy station can save electricity construction investment after peak regulation, in order to quantitatively estimate the saved investment, facilitate the overall planning o...

Abstract

The invention provides a peak-load regulation assessment method based on distributed energy resource station access. The method includes the peak clipping result analyzing step, wherein according to electric power daily load data of a preset user area, the starting time section and the peak-load regulation operation mode of a distributed energy resource station are set, and dynamic regulation is performed on the starting time section and the peak-load regulation operation mode according to the peak and valley difference reduction value of the user area. The invention further discloses a corresponding peak-load regulation assessment system based on the distributed energy resource station access. The peak-load regulation capacity of the distributed energy resource station can be assessed and analyzed in a quantification mode, so that the effect of performing peak-load regulation on a power grid is maximized, power supply pressure at a peak period is effectively buffered, and the utilization rate of power transmission and distribution equipment is improved; moreover, electric power construction investment saved for the distributed energy resource station can be estimated in a quantification mode, the overall planning of the power grid is facilitated, construction is not repeated, and it is guaranteed that the system operates economically and reliably.

Description

technical field [0001] The invention relates to the field of electric power dispatching automation, in particular to a method and system for evaluating peak regulation based on distributed energy station access. Background technique [0002] Since electric energy cannot be stored, when the power grid reaches the peak of power consumption, the power demand is generally met by increasing the output of the generator set or suppressing the load. The daily load curve of electric power is uneven. There will be several peak and valley loads in one day, and the difference between the peak load and the valley load of the load curve is very large, which requires the system to have a peak-shaving unit with a large capacity. With the rapid development of power grid load, the peak-to-valley difference of the power grid is getting bigger and bigger, and the contradiction between the peak-shaving capability of the power grid and the objective peak-shaving demand is very sharp.
