This study aims to propose an alternative hybrid approach model renewable energy sources (RESs), which provide the most reliable results in comparison with existing simulating tools. Within framework of this approach, a specialized processor for modeling converter-interfaced generation (CIG) is developed. describes its structure and validation test system by comparing commercial tools, also presents experimental studies operation as parts practical power system. The obtained confirm adequacy...
Reliability and survivability of electric power systems (EPS) depend on transient stability assessment (TSA). One the most effective way to TSA is time-domain simulation. However, large-scale EPS mathematical model contains a stiff nonlinear system high-order differential equations. Such cannot be solved analytically. At same time, numerical methods are imperfectly applied for such due limitation conditions. To make it appropriate, simplified additional limitations used. These...
Abstract Currently, the number of distributed generation (DG) objects in world is growing mainly due to renewable energy sources (RES). However, integration a large volume DG based on RES into existing electric power systems (EPS) associated with significant problems. For comprehensive study and solution these problems, it necessary carry out detailed simulation real EPS, which not always feasible help tools. Therefore, article proposes use an alternative – Hybrid Real-Time Power System...
The share of the wind turbines (WT) and power generation in general is steadily increasing electric systems (EPS). To solve different issues associated with designing operating WTs EPS, reliable information about all possible modes processes EPS needed. Software hardware-software simulation tools inevitably use numerical integration methods to calculate EPSs, which have its well-known limitations simplifications, so reliability results obtained via such some cases can be insufficient. aim...
