Problems solved by technology

The current AGC is based on the AGC scheduling of thermal power, and the scheduling measures of the auxiliary output of the electric heat storage element are not included in the AGC scheduling control. The thermal element is included in the AGC scheduling, resulting in a deviation in the combination of the two, which cannot better increase the consumption of new energy
[0004] Since the conventional AGC adjustment can only adjust the output of thermal power units, and because clean energy generates a large amount of power and is seriously wasted, in order to accommodate new energy as much as possible, an AGC scheduling control method with flexible load participation is proposed

Embodiment Construction

[0043] Firstly, the thermal power generation of the system P G , clean energy power generation P n , and the load P D For measurement, the thermal power generation is based on the daily power generation requirements of the thermal power plant according to the recent plan, and relies on real-time power consumption, and uses AGC automatic power generation control to adjust the thermal power unit in real time. Its data is mainly displayed through the interface of the dispatching platform through the data uploaded by the thermal power plants to the dispatching terminal, so as to obtain the total power generation P of the region. G , clean energy power generation is mainly divided into photovoltaic power generation P n1 and wind power P n2 The acquisition of this data is mainly through the comparison of similar weather data in the past and light and wind forecasts within 15 minutes to obtain ultra-short-term power forecasts. The platform displays clean energy power generation P...

Abstract

The invention relates to a flexible load dispatching control method for AGC. According to the invention, flexible loads are adopted to participate in system dispatching, the flexible loads are taken as control objects, the balance between the loads and a power supply is achieved by adopting a dispatching method applicable to the type of loads, the coordinated operation between the flexible loads is realized, the maximum consumption of clean energy is realized, and the waste is avoided. A consumption region utilizes the scheme to store heat and consumes generated electric energy. The kind of source-load interaction is an active behavior, and changes a situation that the power supply passively adapts to the loads in the past. When the flexible loads cannot meet the power excess, a buffer region abandons the consumption of partial new energy.

Description

technical field [0001] The invention belongs to the field of power system active power dispatching, and relates to an AGC flexible load dispatching control method. Background technique [0002] The installed capacity of new energy in the "Three North" region is large and widely distributed, and the problem of new energy consumption is particularly prominent. The regulation of the power grid is facing new challenges. The traditional dispatching operation control mode can no longer meet the demand for future power, which shows to a certain extent that wind power has potential. The "load" of anti-peak-shaving characteristics further increases the load peak-valley difference, affects the load characteristics of the system, and makes the system increase more rotating reserves to ensure the consumption of local wind power. How to reduce the abandonment of wind and light caused by the insufficient regulation capacity of the power system and promote the consumption and utilization o...
