The integration of renewable energy sources is one of the promising directions in the development of modern electric power systems. However, the use of such facilities is associated with a number of issues, which are sufficiently critical for both the integrated facilities themselves and the existing power systems. One of these problems is a significant change in the behavior of transients in the power systems with a large share of renewables. This fact is primarily associated with a decrease in the total inertia of the system due to the introduction of converter-connected generation based on renewable energy sources, in particular, integration of Type-4 wind turbine generators. The appropriate tuning of automatic voltage regulators and power system stabilizers of synchronous generators installed at conventional power plants taking into account actual operating conditions can be proposed as a solution to indicated issue to enhance stabilization of power systems with high renewable energy penetration. The article suggests using the Hybrid Real-Time Power System Simulator to implement adequate and comprehensive tuning for such automation. [ABSTRACT FROM AUTHOR]

Mathematical modeling of wind power plants is an urgent task, since the degree of their introduction into traditional energy systems is growing every year. At the same time, it is not always possible to obtain information about the processes in the power system. In such cases, it is possible to use the model of the power system. However, since the power systems are enormous, their model is also great, and therefore, with its detailed reproduction, many problems arise. One solution to such problem is to use simplified wind turbine models. The article substantiates the need to use detailed models of wind turbines to analyze their impact on the functioning of the power system. [ABSTRACT FROM AUTHOR]

Today mathematical simulation is practically sole method, with no alternative, for obtaining comprehensive and reliable information about regimes and processes in electrical power systems. This is due to the impossibility of making field tests in real EPS, and significant limits of physical models. Therefore, according to official standards and regulatory documents of JSC “SO UPS”, the development of the hardware-software simulators for real-time power system simulation with the purpose of automatic voltage regulators setting and certification is the most urgent issue. This paper proposes the Hybrid Real-Time Power System Simulator usage as the solution. The performed studies and tests (partially demonstrated in the article) show the possibility of such simulator usage for the stated aims. [ABSTRACT FROM AUTHOR]

The article considers the problem of the correct operation of the out-of-step protection operation in electric power systems with wind power generators. The relevance of the subject under study is confirmed by a literature review. To solve the problem, a concept has been developed based on a hybrid approach to power systems simulation. The application of this concept will allow for a case of injection wind turbines into the power system to correctly configure out-of-step protection devices. [ABSTRACT FROM AUTHOR]
