Abstract

A coordination control method of wind accumulation is characterized in that according to response of wind turbine generation set rotor control, pitch control and energy storage control to the technical economic characteristics of time, rate of power, volume, cost and the like, operation status data of a wind power plant, a wind turbine generation set, an energy storage system and an electric power system can be collected in real time. The best operating economy of wind accumulation operation is chosen as an aim. The rotor speed of the wind turbine generation set, the pitch angle and the physics limit of the energy storage system are regarded as constraint conditions. Start order, output power, lasting time and quit order of the wind turbine generation set rotor, the winder turbine generation set pitch angle and the energy storage system are coordinately controlled. Wind accumulation frequency modulation requirements and a power grid dispatching power order of an electrical power system are satisfied with the lower volume of stored energy. A Wind discharging rate of wind generating is reduced and economic benefit of wind accumulation is improved.

Description

technical field

[0001] The invention relates to a coordinated control method of an energy storage power station and a cluster of wind farms. Background technique

[0002] At present, the worldwide energy shortage and greenhouse effect are seriously perplexing human development. In order to solve the above problems, countries around the world support the large-scale development and application of renewable energy from technology, policy and finance. Wind power has been rapidly developed at home and abroad due to its advantages of high technological maturity, low cost, and large-scale development and application.

[0003] Affected by factors such as weather changes, unit characteristics, and wake effects, wind power is volatile, random, and intermittent. Large-scale wind power grid integration poses new challenges to grid planning, voltage regulation, frequency control, and dispatching operation modes. In order to ensure the reliable, safe and economical operation of the pow...
