Abstract

The invention discloses a wind power generation and adjustable load unified operation system. The system comprises a wind power generation unit, a power distribution network, a controlled load, a hybrid energy storage module and an energy optimization manager, wherein the wind power generation unit adopts a distributed small-sized wind power set or centralized high-capacity wind power set and is used for providing clean energy for the power distribution network; the controlled load is used for carrying out classification of an electric load, a heat load, other loads and the like according to load important influence degrees and performing local control through a load controlled terminal; the hybrid energy storage module is used for determining the proportion of a power type and an energy type according to the load important influence degrees and ensuring an important load to continuously supply power; and the energy optimization manger has the functions of load prediction, power generation prediction, data monitoring, power allocation, fault diagnosis, fault alarm and the like. Wind power fluctuation is suppressed to the greatest extent by fully utilizing the controlled load, and coordinated control operation between the wind power generation and the adjustable load is achieved.

Description

Technical field: [0001] The invention relates to a wind power generation and adjustable load combined operation system, which belongs to the technical field of wind power generation. Background technique: [0002] With the large-scale development of wind power, the issue of grid integration and consumption of wind power is currently a hot issue that the wind power industry is most concerned about. Because wind power has the characteristics of randomness and volatility, large-scale wind power grid connection puts forward higher requirements on the peak shaving and absorption capacity of the grid. In some areas, the power load of the grid is insufficient, and the flexible adjustment power supply is less, and wind power consumption Difficulties in acceptance. [0003] With the continuous development of technology, the load side participates in power grid dispatch, which can provide a certain amount of reserve capacity for the power system. For a controllable load with certain energy...
