Model Based Systems Engineering

This paper presents a model of hybrid photovoltaic-wind power system based on SysML (System Modeling Language) which is a modeling language in supports to Model Based Systems Engineering (MBSE) practices. MBSE refers to a formalized procedure of systems development through the application of modeling principles, methods, languages and tools to the complete lifetime of a system.  Broadly speaking, the modeling of power systems is performed using software such as Matlab/Simulink, DigSilent, PowerWorld, ETAP, etc. These tools allow modeling considering a particular point of view depending on the objective that is to be assessed. SysML offers different aspects ranging from specifications and requirements, structure and behavior. This study focuses more specifically on the structural and behavioral modeling of hybrid photovoltaic-wind system; the main objective is to demonstrate the use of SysML in power systems’ modeling by developing models capturing the system’s major requirements, the structure and connection between entities, the interaction between stakeholders and the system itself and lastly, the system’s behavior in terms of transition between states.

The Difference

Wind power is a kind of special electric power, because of the volatility of the wind, making voltage stability has become an important research problem wind power system must facing with. Therefore, according to the relevant current research status and the main existent problems of wind power system, expounding the difference of voltage stability between the conventional energy sources and the wind power, and the influence of voltage stability to the power system which caused by wind power system. This paper mainly from the definition and the classification to introduce the voltage stability; from the research contents and methods of static and dynamic voltage stability to analyze power systems which contains wind farms, especially emphasizing the necessity of the bifurcation theory used in power system contains wind power. Finally points out that the research trend of analysis and improvement in this area.

Wind Power System

With wind farm capacity continuously increasing, remarkable characteristics of wind power make nonlinear dynamic characteristics of wind power system more apparent than conventional power system. Domestic and international experience shows that the voltage instability is main forms of wind power system instability. The bifurcation theory is one of the most powerful tools in analysis of structure stability of nonlinear dynamic system. Therefore application of bifurcation theory not only reveals the voltage stability mechanism, but also has important theoretic value and practical value for the security analysis of the whole power system, especially for voltage stability of wind power system.

Non Linear System

It has been found that there is a very complex and chaotic phenomena in the power system and other nonlinear system. Chaos is a very complex phenomenon caused by the interaction of the parameters in nonlinear systems, its appearance will accompany the non-periodic、seems to be without rules、sudden or paroxysmal mechanical and electrical oscillation of the system, which will cause widespread blackout and disintegration of the system when the oscillation becomes serious. Therefore, due to the wind power system is a typical large-scale complex non-linear system, so that chaotic phenomena will also occur under certain conditions and chaos will influence the stable operation of the wind power system, so the chaotic research are particularly important along with the fast development of grid-connected wind power technology.
