Embodiment Construction

[0023] Below in conjunction with specific embodiment the present invention is described in further detail:

[0024] An automatic demand response strategy based on maximum power supply capacity, including the following steps:

[0025] Step 1. Calculate the maximum power supply capacity TSC of the current network through the TSC calculation model 0 .

[0026] In this step, the maximum power supply capacity of the current network can be calculated by reflecting the TSC calculation model based on the feeder interconnection relationship. The TSC calculation model is shown in formulas (1)-(7):

[0027] MaxTSC=∑P i (1)

[0028]

[0029] In the above formula, P i Indicates the load carried by No. i main transformer;

[0030] f m Indicates the load carried by the m-th feeder;

[0031] trf mn Indicates the feeder m N-1 The load transferred to the feeder n at time;

[0032] trt ij Indicates the load of main transformer i that N-1 transfers to main transformer j;

[0033] ...

Abstract

The invention relates to an automatic demand response strategy based on maximum power supply capability. The automatic demand response strategy is characterized by comprises the steps of calculating and obtaining the maximum power supply capability of a current network through a TSC calculation model, judging whether a current load satisfies a feeder N-1 constraint through a feeder N-1 constraint model, and calculating and obtaining a load control mode with a minimal load regulation mode through a load regulation model and regulating a power distribution network. According to the automatic demand response strategy, through the maximum power supply capability of the current network, whether the current load satisfies the feeder N-1 constraint is judged and power distribution network whose grid expected load exceeds grid maximum power supply, a demand side response strategy based on the maximum power supply capability is realized, thus a power demand side user optimizes a power use mode, the rational allocation and efficient use of demand side resources are promoted, the peak and valley difference of the grid is improved effectively, and the ability of power supply and demand balance is improved.

Description

technical field [0001] The invention belongs to the technical field of electric energy management, in particular to an automatic demand response strategy based on maximum power supply capacity. Background technique [0002] As the core element of the national energy strategy, electricity is the lifeblood of the national economy. With the continuous improvement of the modernization of the national economy, the seasonal and time-period loads have increased rapidly, the peak load of the power grid has continued to rise, and the peak-to-valley difference of the power grid has gradually expanded. The imbalance between power supply and demand in some areas has seriously affected the safe and stable operation of the power system. . The traditional way to meet the peak load demand of the power grid is to increase the installed capacity of the power grid, which passively causes huge pressure on investment in power generation, power transmission and transformation, and power distribu...
