Coordinated load control system and method for wind power generation and thermal power generation groups

Abstract

The invention discloses a wind power generation and thermal power generation set group load coordinated control system and method. The system comprises a wind power generation load change calculationmodule, a thermal power generation load dynamic compensation instruction calculation module and a thermal power generation set group dynamic adjustment module. The wind power generation load change calculation module is used for calculating the wind power generation load change quantity. The thermal power generation load dynamic compensation instruction calculation module is used for calculating the compensation load instruction of the thermal power generation set group when the wind power generation load changes according to the wind power generation load change quantity. The thermal power generation set group dynamic adjustment module dynamically adjusts the power generation load set value of the thermal power generation set according to the compensation load instruction of the thermal power generation set group. The actual output of the thermal power generation set group can be changed by dynamically adjusting the power generation load set value of the thermal power generation set according to the wind power generation load change quantity so that the load stability of the regional power grid can be maintained and the power supply quality of the power grid can be enhanced.

Description

technical field [0001] The invention relates to the technical field of load coordination control of generator groups, in particular to a load coordination control system and method for wind power generation and thermal power generation groups. Background technique [0002] With the rapid development of wind power installed capacity, the proportion of wind power load in the operating load of the power grid is increasing, especially in areas rich in wind power resources, the proportion of wind power load is even greater. At present, wind power is developing rapidly, and the proportion of wind power load in the power grid is increasing. As a clean energy, wind power has obvious advantages in terms of environmental protection and resource utilization. However, due to natural conditions, wind power generation load is random The volatility is large and the predictability is not strong, which has a great impact on the safe and stable operation of the power grid.

At present, wind power is developing rapidly, and the proportion of wind power load in the power grid is increasing. As a clean energy, wind power has obvious advantages in terms of environmental protection and resource utilization. However, due to natural conditions, wind power generation load is random The volatility is large and the predictability is not strong, which has a great impact on the safe and stable operation of the power grid

[0003] In regional power grids with concentrated wind power loads, the rotating reserve capacity in the power grids is less and less. In some regional power grids that lack flexible frequency regulation means, the randomness of wind power loads has more and more obvious impact on the power grids. The existing generator sets The load coordination control system of the group cannot fully absorb the wind power and other new energy power loads, and cannot guarantee the power supply quality of the power grid and the safe and stable operation of the power grid
