Description
Technical Field
The invention relates to the technical field of real-time simulation of wind power plants, in particular to an in-loop test adjustment system and a test method for energy storage hardware of a wind power plant.
Background
Due to the characteristics of wind energy randomness and fluctuation, the output power of the wind power plant is determined to also show fluctuation and uncertainty. With the gradual increase of the proportion of the capacity of the wind turbine generator in the power system, not only is the wind power output difficult to accurately predict, but also a series of problems are brought to the safe and stable and economic operation of the power system. In order to stabilize wind power fluctuation power, wind power has schedulability to a certain extent, and energy storage equipment is often connected into the system as a mode for guaranteeing safe and stable operation of the system. Whether the capacity configuration of the energy storage system is reasonable or not has great influence on the economic operation of the wind farm energy storage combined system. If the energy storage capacity is configured to be too small, the wind energy resources are rich at night, and when wind electricity is generated greatly, the generated surplus electric quantity cannot be stored fully, so that the waste of the wind electricity resources is caused. If the capacity allocation is too large, not only the investment cost is greatly increased, but also the energy storage equipment can be in the state of insufficient charging for a long time, and the service life of the energy storage equipment is seriously influenced. Therefore, the reasonable planning of the capacity of the energy storage system has very important practical significance for the long-term development of the wind power generation industry.
In the prior art, for example, the Chinese patent literature with publication number of CN104317283A and publication time of 2015 1 month and 28 days, named as "a hardware-in-the-loop test platform for a wind farm control system and a test method thereof", discloses a hardware-in-the-loop test platform for the wind farm control system and a test method thereof, wherein the test platform comprises a core power grid, a central computer simulation computer of a converter, a pneumatic and mechanical simulation computer cluster of a wind turbine, a state monitoring and operating upper computer of the test platform, a gateway and interface module, a wind farm control system and the like, and high-speed Ethernet communication is adopted between the upper computer and each simulation machine and between the simulation machine and the tested wind farm control system. The test platform is based on a Matlab/Simulink wind power plant control system simulation test platform, and can repeatedly simulate the conventional and fault working conditions of a wind power plant by combining a real wind power plant controller to perform corresponding hardware-in-loop test. However, the test platform does not build an energy storage system model, so that the hardware-in-the-loop test cannot be performed on the energy storage capacity of the wind power plant.
In addition, as disclosed in chinese patent literature of publication No. CN104505850a, publication No. 2015, 4/5, entitled "a wind farm energy storage system", a wind farm energy storage device control system is provided, which makes and implements an optimum control strategy by predicting the change conditions of the power generation and load of a wind farm, and detecting the battery capacity of an energy storage battery module and the operation condition of a power distribution network in real time. However, the system is based solely on software simulation and cannot test a real energy storage system energy manager.
