Abstract

The invention aims at the defect of an existing network-province two-level automatic generation control (AGC) dynamic optimization dispatching method, and proposes a two-layer planning-based network-province two-level coordinated dispatching method of an AGC machine set. By the two-layer planning-based network-province two-level coordinated dispatching method, coordination among different interest bodies of a network dispatcher and each provincial dispatcher can be achieved, network-province two-level frequency modulation responsibility is determined, safety constraint and assessment index are met, and minimum total cost is simultaneously achieved.

Description

technical field [0001] The invention belongs to the field of frequency modulation and automatic power generation control of interconnected power grids, and in particular relates to a method for coordinating and dispatching two-level AGC units in a network and a province based on two-level planning. Background technique [0002] Automatic Generation Control (AGC) is an important part of the energy management of modern power systems. Its basic task is to maintain the active power balance of the grid by controlling the output of AGC units, thereby ensuring the frequency quality of the system and maintaining the inter-regional energy balance. Electric power exchange plan and facilitate the real-time economic distribution of active power. With the gradual interconnection of ultra-high voltage regional power grids in my country, it is a very realistic topic to study the AGC control strategy of the interconnected grid to ensure the frequency quality of the grid, especially the coor...
