Modeling method for active and reactive power control system of wind-solar-storage power station based on measured data

Abstract

The invention discloses an actually-measured data based modeling method for an active power and reactive power control system of a wind-light power storage station. The method comprises the following steps of acquiring and classifying data of each single device of a large-sized wind-light power storage station, and acquiring the number of single stations, active power adjustment capacity, time and adjustment accuracy of the single stations, and reactive power adjustment capacity, time and adjustment accuracy of the single stations; separately building a wind power plant model, a photovoltaic power station model and an energy storage power station single-station model for the large-sized wind-light power storage station; building an integrated circuit model, a main transformer model and an equivalent circuit model for the large-sized wind-light power storage station, adjusting parameters of a static var generator (SVG), a static var compensator (SVC), a capacitor bank and a reactor bank so that the external characteristics of the SVG, the SVC, the capacitor bank and the reactor bank are consistent with the actual working condition of the large-sized wind-light power storage station; and carrying out time-domain simulation on the above models to acquire a layered control system model of the large-sized wind-light power storage station.

Description

technical field [0001] The invention belongs to the field of power system operation and new energy technology, and in particular relates to a modeling method for active and reactive power control systems of large-scale wind-solar storage power stations based on measured data. Background technique [0002] At present, new energy represented by wind power and photovoltaic power generation is gradually becoming an important power energy resource in China, playing an important role in meeting energy demand, improving energy structure, reducing environmental pollution, protecting the ecological environment, and promoting economic and social development. [0003] Due to the characteristics of randomness, volatility and intermittency of wind power and photovoltaic power generation, and technical bottlenecks in forecasting, dispatching and control, the independent power generation characteristics and source-network coordination of new energy sources are quite different from conventio...

Problems solved by technology

[0003] Since wind power and photovoltaic power generation have the characteristics of randomness, volatility and intermittency, and there are technical bottlenecks in forecasting, scheduling and control, the independent power generation characteristics and source-network coordination of new energy are quite different from conventional power.
