太陽(yáng)能光伏發(fā)電系統(tǒng)中關(guān)鍵控制問(wèn)題的研究
[Abstract]:Since the 1980s, with the acceleration of industrialization and the rapid development of the global economy, the demand for energy has increased sharply, so the total amount of fuel needed by people has also increased rapidly. The limited fossil energy has become increasingly unable to meet the needs of people. The global energy crisis and environmental pollution have made it an inevitable trend to develop new energy sources, such as tidal energy, nuclear energy, solar energy, and so on. As a new energy field, the related aspects have been widely paid attention to by all walks of life, so the professional research on them has been gradually strengthened. Among them, solar energy has a great advantage in these renewable energy sources, and its unique properties have been attached great importance to by countries all over the world. Under this background, this paper takes the solar photovoltaic system as the research object, through the analysis of the solar photovoltaic power generation system, we can see the control problems, including photovoltaic array model, maximum power point tracking. The control strategy of converter. The main work and results of this paper are as follows: 1. On the basis of analyzing the working principle and external characteristics of photovoltaic array, this paper introduces a dynamic model of photovoltaic array, which can simulate the environmental temperature, illumination intensity and other parameters that can be affected by the environment. Provides the simulation foundation for the concrete theory analysis and the control method research. 2. This paper analyzes, studies and compares the common maximum power point tracking control algorithms, summarizes their advantages and disadvantages, and verifies the effectiveness of tracking control under different light intensity and temperature. 3. The design of global sliding mode control for DC/DC converter is studied. The application of DC/DC converter in photovoltaic power system is very extensive. In this paper, the basic DC/DC converter is taken as the research object and the suitable sliding mode surface is selected. A new controller design method of exponential approach law is introduced. By adjusting the control parameters, a better control effect is achieved and the dynamic performance is balanced. 4. The chaos control problem of DC/DC converter is studied, and the chaos problem in DC/DC converter is studied. The state feedback control method is used to control the chaotic DC/DC converter effectively. The stability of the system is enhanced.
