Abstract

The invention discloses a household load classification power grid friendly response control method. The method is characterized by enabling frequency response state of a power grid to be stepped through monitoring frequency and frequency fluctuation change rate of the power grid in real time; classifying household load into adjustable load, interruptible load and remindable load according to the performances of household appliances; and according to the relation between power grid real-time frequency and stepped frequency value and relationship between the power grid frequency fluctuation change rate and response indexes, realizing a control strategy that various loads friendly responds to the corresponding state frequency actively. According to the method, the function that the household load friendly responds to the grid frequency initiatively is achieved, thereby not only meeting power utilization experience of users, reducing operation cost of grid companies, but also improving construction of smart power grids and realizing the purpose of energy saving and emission reduction.

Description

technical field

[0001] The invention belongs to the field of smart grids, in particular to a family load classification friendly response control method based on step frequency response. Background technique

[0002] With the increasing development of the national economy, the demand for electricity has increased significantly and the problem of global resource shortage has become increasingly prominent. The development and application of new energy has become a consensus, but it also brings challenges to the stable operation of the power system. The traditional way of mobilizing the power of the standby unit, supplemented by conventional low-frequency load shedding, power cuts and other measures, will help maintain the stability of the power grid, but it will increase the operating cost of the power system or affect the user's power consumption experience.

[0003] As early as 2002, Professor Thiringer of Sweden first proposed the concept of "grid-friendliness". The load-si...
