Embodiment Construction

[0030] The present invention is described in further detail below:

[0031] The invention discloses a method for dispatching virtual peak-shaving units based on automatic demand response. In the method, in the demand response center, from the power grid level, the user combination and capacity participating in the dispatch are sorted and fitted; Combined fitting of electrical equipment and power; the demand response center can also directly fit equipment with large adjustment capabilities. Among them, the virtual peak-shaving unit refers to the adjustable load dispatched, and the unit fitting refers to the participating Load selection and capacity. In the grid demand response center, the fitting of the virtual peaking unit refers to the user or equipment combination and adjustment capacity participating in the response. The fitting content includes: user identification, response start time, load adjustment capacity, and response end time; on the user side, the virtual The pea...

Abstract

The invention disclose a virtual peak adjustment set scheduling method based on an automated demand response. A fast adjustable load on a user side is used as a virtual fast peak adjustment set to participate power grid interactive operation; a user automatically collects responsible capacity and uploads information to the power grid in real time and provides a feedback of a participation state through a bidirectional interaction information model between the power grid and the user. The power grid performs capacity fitting and issues execution. The virtual peak adjustment set scheduling method based on the automated demand response can provide a virtual peak adjustment standby resource through fast and effective adjustment and control on an adjustable load on the user side. When electricgeneration output is hard to satisfy the needs of fast increased loads, the load in the scheduling area can fast adjust electricity consumption, reduces load and can alleviate power supply tension ofthe power grid as a virtual rotation standby set.

Description

technical field [0001] The invention relates to the field of power grid dispatching, in particular to a method for dispatching virtual peak-shaving units based on automatic demand response. Background technique [0002] After years of development, my country's power grid dispatching has made considerable progress. A dispatching automation system consisting of a highly reliable basic platform and four major applications of "real-time monitoring and early warning, dispatching management, dispatching plan, and safety check" has been established to realize It ensures the reliable scheduling and management of the power grid, and effectively guarantees the safety and economy of the power grid operation. Since the power supply and demand must be balanced in a timely manner, a certain reserve capacity must be reserved in the system to avoid stability damage caused by the forced outage of the generator set and the fluctuation of load uncertainty. important issues to consider. [000...
