Embodiment Construction

[0028] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0029] The multi-type energy layered coordination control method based on new energy consumption described in the present invention is applied to an automatic power generation control system including multi-level control areas of national dispatch, sub-center, and provincial dispatch. The system monitors computers, channels, and remote The terminal, distribution device, and generator automation device form a closed-loop control system to monitor and adjust the frequency of the power system to control the output of the generator. The following coordinated control method is executed by the above-mentioned control system. It should be pointed out that the present invention does not propose a new calculation scheme for the calculation method of power allocation of a specific type of section, and the power allocation algorithms unde...

Abstract

The invention discloses a multi-type energy hierarchical coordination control method based on new energy consumption. According to the method, through a multi-energy coordinated control scheduling operation control method of a multi-stage control area, the master station access and the active automatic control of the large-scale new energy of a power grid are realized; by coordinating the controlstrategies, and coordinating a conventional unit and the new energy units, such as the wind power photovoltaic units, etc., the functions of frequency modulation, peak regulation, tie line control, section control, replacement transaction control and the like of the power grid are realized, the output of the conventional unit is optimized, the power grid accepts the new energy output to the maximum extent on the premise of guaranteeing the safety of the power grid, the real-time control problem during the large-scale new energy access process is effectively solved, the effective support to thelarge power grid is realized, and the operation safety and economical efficiency of the power grid are improved.

Description

technical field [0001] The invention relates to a power grid scheduling control method, in particular to a multi-type energy hierarchical coordination control method based on new energy consumption. Background technique [0002] With the rapid growth of the power grid scale and the addition of various new energy sources, UHV DC supporting power supplies have been put into production one after another. The power grid will have a joint control of national, sub-center, and provincial multi-level control areas, and multi-type power sources such as wind, water, fire, and light in the control area. Interweaving, complex control strategies and assessment requirements within the control area, control interval, new energy alternative transaction control, and contact line control. Dispatchers are under increasing pressure to regulate and control work, and it will gradually become difficult to adapt to the mode of mainly relying on manual dispatching. The power grid including large-sc...
