Automatic demand response operation mode based on flexible load control

Abstract

The invention discloses an automatic demand response operation mode based on flexible load control. The automatic demand response operation mode based on flexible load control comprises steps of providing demand response services in different time scales like peak clipping, virtual peak adjustment and standby service through performing flexible control on a flexible load according to different load management goals. The flexible load has a remote controllable and adjustable capability and can fast respond to a demand response signal. The flexible control comprises operation mode adjustment, operation parameter adjustment and operation mode adjustment. The operation mode adjustment reduces a quantity of redundant devices in operation. Operation parameter adjustment is to change part of operation parameters of a device and appropriately reduce input power of the device. The operation mode adjustment is to transfer or reduce load output through reasonably adjusting operation time and a working state of the device. The automatic demand response operation mode based on flexible load control improves device operation efficiency and service life and reduces pressure on control of a rigidload in orderly power utility.

Description

technical field [0001] The invention relates to the field of optimal distribution of power resources, in particular to an automatic demand response operation mode based on flexible load control. Background technique [0002] With the structural adjustment of the national economy, the daily average peak-to-valley difference and seasonal peak-to-valley difference of the power grid load are increasing, the adjustable reserve resource capacity of the power grid is becoming more and more limited, and administrative power cuts are still very serious. At the same time, the increasing variety of load types and characteristics, as well as the massive access of distributed power sources and electric vehicles, have brought greater impact on the peak and valley load fluctuations of the power grid. Therefore, demand response must be implemented to effectively alleviate the peak shortage of power supply, further improve the utilization efficiency of power grid assets, and delay the invest...

[0005] But at the same time, we also see that domestic demand-side management, especially demand response, is still in its infancy, and a reasonable electricity price or incentive mechanism has not yet been established. Demand-side management relies more on administrative means, and load management means are relatively single

The traditional rigid load control method is mainly aimed at rigid loads. The control method is simple and extensive, which affects the fairness and justice of demand side management. The degree of automation and enthusiasm of power users to actively participate in grid load adjustment is not high, and the degree of user participation is low.
