A Real-time Coordinated Control Method for Multiple Interruptible Loads Considering Market Operation Rules

Abstract

The invention discloses a multiple-interruptible-load real-time coordination control method considering a market operation rule. The method comprises the following steps of 1) carrying out spectral analysis on interruptible loads, according to different demand response time in a distribution network, carrying out detailed classification on the interruptible loads of residents and using a frequency domain to represent each type of interruptible loads; 2) determining a control target and establishing an assessment standard, taking one day as one scheduling period, dividing into 96 point assessment periods, guiding a system to appropriately schedule the interruptible loads, and simultaneously verifying a compensation effect of each assessment period; 3) carrying out real-time demand-based control, according to a power deviation value, using discrete Fourier transformation to calculate scheduling amounts of various kinds of interruptible loads, and under limitation of three control threshold values, compensating a power deviation in real time; 4) correcting a scheduling demand value, and according to an actual condition, adjusting the scheduling amount and a scheduling frequency of each interruptible load; and 5) investigating a correction effect, controlling the assessment standard according to a feed line and investigating the correction effect of each period.

Description

technical field [0001] Embodiments of the present invention relate to the field of control of interruptible loads in power systems, in particular, to a method for real-time coordinated control of various interruptible loads taking market operation rules into consideration. Background technique [0002] The power grid company hopes that the actual value of the load power in the distribution network can flow according to the planned value, and if there is a deviation, it needs to provide auxiliary services. Usually, the backup of my country's power system is composed of a certain proportion of capacity reserved by thermal power or hydropower plants according to experience. practical. In fact, there are few corresponding power regulation measures in my country's distribution network at present, and the power flow is naturally distributed with the load. With the improvement of people's living standards, there are more and more high-power household appliances whose power consump...
