Test method, test platform and test system for wind-photovoltaic-storage hybrid grid-connected power generation

Abstract

A test method for wind-photovoltaic-storage hybrid grid-connected power generation includes the following steps: acquired resource data or power data are provided for a simulated power generation source controller in order to control the output power of the simulated power generation source; the statistic of a load is provided for a simulated load controller in order to control the power of the simulated load; the initial parameters of a wind-photovoltaic-storage hybrid power generation system to be tested are provided for a monitor; the data of each part of the system is acquired, and a comparison diagram is utilized to analyze the reliability of the system; an acquired actual curve is compared with a theoretical curve so as to evaluate whether the system performance meets requirement, and the controllability of the simulated power generation source controller and the simulated load controller is utilized to carry out a reliability test on the system under extreme and faulty conditions. According to the inveniton, the economy and reliability indexes of the wind-photovoltaic-storage hybrid power generation system can be conveniently researched and analyzed.

Description

Technical field [0001] The invention relates to the field of power generation testing, in particular to a wind-solar energy storage combined grid-connected power generation test system. Background technique [0002] Solar energy and wind energy are renewable clean energy bestowed by nature. Solar and wind energy have the characteristics of unlimited reserves, economy and a wide range of existence. [0003] The wind-solar combined power generation system utilizes the complementarity of wind energy and solar energy, such as relatively sufficient wind energy at night, sufficient solar energy during the day, sufficient solar energy in summer, and sufficient wind energy in winter. Therefore, the use of complementarity can reduce the amount of energy storage and improve the economy and efficiency of the system. reliability. The reliability of the system is not only determined by the components, but also by the state of the power grid connecting the entire system and the various control...

Problems solved by technology

In the field of power generation, many generators have corresponding performance test methods and test platforms when they are designed, which can be used to detect whether the design of the generator is reasonable, and then optimize and improve the generator according to the test results, but the existing technology There is no special method and platform for performance testing and analysis of wind-solar-storage combined power generation system in China, which restricts the utilization and development of wind-solar-storage combined power generation system

[0005] The Chinese patent application with the publication number CN200910103683 discloses a performance test method and test platform for a wind-solar-hydrogen integrated energy power generation system. Although the technical solution described in the patent application has completed a set of test devices for specific component types / capacity / performance , but the investment cost is high, and the utilization rate of test equipment is relatively low, and the performance cannot be tested from the level of the entire power grid system, only staying at the level of performance test of system power generation components
