A new energy power generation system model

Abstract

The invention provides a new energy power generation system model, which comprises a machine-network interface module, an active control module, a reactive power control module, a fault control and protection module, and a power supply module. The new energy power generation system model has a typical modular characteristic, wherein the active control module and the reactive power control module cover the specific active and reactive power control strategies, and the specific control strategy switching is realized by changing the control strategy switch logic; the fault control and protection module realizes fault control and protection of each new energy power generation system, and realizes judgment and output of the new energy power generation system fault control and protection logic; and the power supply module realizes the characterization of the model to different types of new energy power generation systems by switching on and off. The model provided by the invention extracts the general characteristics of the new energy power generation systems, so that the model has an obvious modular characteristic, and the workload of the modeling process is reduced.

Description

technical field [0001] The invention relates to a new energy power generation system model, which belongs to the field of new energy power generation modeling and simulation. Background technique [0002] As the proportion of new energy power generation in the power system continues to increase, its impact on the power system is becoming more prominent. Accurate modeling of new energy power generation systems is one of the keys to analyze the impact of large-scale new energy grid-connected stability, safety and reliability. At present, most of the grid-connected interfaces of new energy generation systems such as wind power generation, photovoltaic power generation, and battery energy storage use power electronic devices. The establishment of the mechanism model or the overall system model of each component does not fully consider the common factors in its grid-connected interface and its control system, which increases the complexity of the modeling work and is not easy to...
