Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] A method for constructing a monitoring model of an interruptible load characteristic adapted to network-load interaction of the present invention includes the following steps:

[0020] 1) Select a number of representative users for each type of industry users in the whole network to investigate and determine the composition of their electrical equipment and the capacity ratio of various electrical appliances; divide several typical users in industries into C A fuzzy class and find the cluster center of each class to minimize the weighted error square sum function within the class, adapt to the introduction of fuzzy division, the membership matrix U allows the value to be in the range of 0-1, and obtain the target by deriving all input parameters The function is the minimum necessary condition, from which the optimal fuzzy classification matrix U and cluster ce...

Abstract

Provided is A construction method of interruptible load characteristic monitoring model adapting to network-load interaction. The invention relates to a monitoring field of interruptible load, in particular to a method for constructing a monitoring model of interruptible load characteristics adapted to network-load interaction. An interruptible load characteristic monitoring model is proposed, which can realize source-load friendly interaction and efficient utilization of resources. The invention has the advantages that: By analyzing the characteristics of interruptible load in different industries, the load loss characteristics under the interruptible load interaction mode are studied, and the basis of interruptible load control priority evaluation method is obtained, and the monitoring model of interruptible load suitable for power grid is established to better serve the needs of the development of source-network-load interaction system.

Description

technical field [0001] The invention relates to the monitoring field of interruptible loads, in particular to a construction method of an interruptible load characteristic monitoring model adapting to network-load interaction. Background technique [0002] At present, my country's clean energy industry is developing rapidly, and the installed capacity of wind power and photovoltaic power generation has leapt to the first place in the world. However, compared with traditional coal-fired and gas-fired power generation, the regulation ability of clean energy is poor, and the output has obvious randomness and intermittency, which increases the difficulty of power grid operation. [0003] With the large-scale connection of clean energy power generation to the power grid and the construction of inter-regional UHV transmission channels, the rigidity of power output on the power side of the power system has become more and more prominent. Adapt to new clean energy consumption and s...
