Embodiment Construction

[0044] In order to make the technical problems, technical solutions and advantages to be solved by the embodiments of the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0045] Such as figure 1 As shown, it is a flow chart of the delay-based peak load reduction method in the intelligent power consumption of the present invention, including the following steps:

[0046] (1) The control center issues a peak load reduction command to the load agency; where the command is a 0-1 binary command, indicating whether the load agency is required to implement a load control algorithm for the periodic flexible load in its management area;

[0047] (2) The load agency obtains the power amplitude, duty cycle and period of the periodic flexible load in its management area;

[0048] (3) According to the parameters of the periodic flexible load, the load agency establishes the periodic flexible load model and all the ...

Abstract

The invention provides a delay-based heuristic peak load reduction method, which comprises the steps as follows: a regulation center gives a peak load reduction instruction to a load agency; the load agency obtains power amplitudes, duty ratios and periods of periodic flexible loads within a management region, builds a load model and a peak load reduction model according to parameters of the load, calculates a starting time delay of each periodic flexible load and gives a control signal to electric equipment; and the electric equipment regulates the starting time according to time delay parameters after receiving the load control signal. A small phase delay is exerted in a work period of the intelligent electric equipment, so that reduction of overlapping of periodic loads and minimization of the maximum overlapping value of periodic pulse waves are achieved to achieve peak load reduction.

Description

technical field [0001] The invention relates to the field of household load control in smart grids, in particular to a delay-based heuristic peak load reduction method in smart electricity consumption. Background technique [0002] ICT has penetrated into grids and building units to provide energy management and load control for essential infrastructure. One of the most important features of the smart grid is to provide support for data flow and command flow through a two-way communication link between the user and the grid operator. Smart devices are deployed at the user end to provide user interfaces from smart devices to the smart grid. New standards and smart sensor / actuator networks have been applied to the communication infrastructure between smart grids and smart devices, and support the most basic operations in smart grids, providing power services such as load control and demand response. A smart grid consists of controllers that monitor a group of smart buildings...
