考虑孤岛微网情况下的低频减载策略研究
[Abstract]:The purpose of this paper is to study the theory of low-frequency load reduction scheme under isolated island microgrid, and to control the disturbance caused by emergency events. The significance of this paper is to ensure the stability of power system. The first chapter is the full text of the introduction. In this section we will discuss what is a microgrid why the meaning of the condition and what is the low-frequency load reduction and why this method is used. In the second chapter, we will discuss the related microgrid models. In this part, the distributed power supply is introduced, each component of the distributed power supply is analyzed mathematically, and the islanding model of PV, synchronous motor is simulated. Most modeling is based on information contained in photovoltaic power generation. In the third chapter, there are two parts. First, we will discuss the concept of electrical interference, and then we will discuss the low-frequency load reduction strategy for isolated microgrids. The fourth chapter is the conclusion of this paper. In this section, we will describe in detail the research carried out under this project. It includes the availability and software of the model, the behavior analysis of the electrical effects of distributed generation on the power system and the selection of the best theory of low-frequency load reduction strategy.
