“…The detailed description and different performance parameters, such as the reaction time and execution time distribution of program operation via the microcontrollers used in the HRTSim, are shown in the work of Andreev et al [23]. The reliability of the information obtained via HRTSim has been confirmed through the extensive laboratory studies and validations with field measurements [26][27]. The generic structure of HRTSim is shown in Fig.…”

This study aims to propose an alternative hybrid approach to model renewable energy sources (RESs), which provide the most reliable results in comparison with the existing simulating tools. Within the framework of this approach, a specialized hybrid processor for modeling converter-interfaced generation (CIG) is developed. This study describes its structure and validation in the test system by comparing the results with commercial modeling tools, and also presents experimental studies of its operation as parts of the practical power system. The results obtained confirm the adequacy of the developed tools.

“…Today EPS of the Tomsk region consists of asynchronously operating northern and southern parts, the operational section between which passes through the transit of 220 kV with length of 797.3 km (including the territory of the united power system (UPS) of Siberia -785.7 km) between SS Tomskaya (UPS of Siberia) -SS Volodino -SS Parabel -SS Sovetsko-Sosninskaya -Nizhnevartovskaya GRES (UPS of Ural) [45]. In normal operating state, the operational section is located on the area between SS Vertikos -SS Parabel.…”

Reliability and survivability of electric power systems (EPS) depend on transient stability assessment (TSA). One of the most effective way to TSA is time-domain simulation. However, large-scale EPS mathematical model contains a stiff nonlinear system of high-order differential equations. Such system cannot be solved analytically. At the same time, numerical methods are imperfectly applied for such system due to limitation conditions. To make it appropriate, the EPS mathematical model is simplified and additional limitations are used. These simplifications and limitations reduce reliability of simulation results. Consequently, their validation is needed. The most reliable approach to provide it is to compare the simulation results with the field data. However, in practice, there are not enough data for such validation. This paper proposes an alternative approach for validationthe application of a reference model instead of field data. A hardware-software system HRTSim was used as a reference model. This power system simulator has all the necessary properties and capabilities to obtain reliable information required for comprehensive validation of transient stability calculations in EPSs. Main disturbances leading to instability in EPSs are investigated to conduct the validation (processes in cases of faults, single-phase auto-reclosing operation and power system interconnection). Fragments of corresponding experimental studies illustrate the efficiency of the proposed approach. Obtained results confirmed the possibility of the developed approach to identify the causes of numerical calculation errors and to determine disturbances calculated with the significant error. In addition, experimental studies have revealed that numerical calculations error depends on disturbances intensity.

Recently the raise in interconnection of the power system leads to vigorous change of power flow, as well as load in tie-line. Hence, there is a need of robust control in both tie-line power flows and systems frequency. This research work aims to design a dual-mode switch controller-based load frequency control in multi-area interconnected power system (MAIPS). In this, the incremental control action's influence is taken along with the constraints of the system dynamic such as Governor with Dead Band, Capacitive Energy Storage, and Generation Rate Constraint. This work on the proposed controller of the multisource-MAIPS (MS-MAIPS) is operated on the basis of dual mode switching function. For this purpose, a threshold value 𝜉 is evolved. The control on MPC and optimized hysteresis modulation based sliding mode control (HMSMC) is varied according to this switching function. For attaining the fascinating performance, the optimal tuning of switch threshold 𝜉 and the gain of HMSMC controller K is exploited by a new Self-Adaptive Sea Lion algorithm. To the end, variation of control parameters like T r , T rb , C g , as well as T CD for reducing unwanted variances in power flows among control areas is used to verify the effectiveness of the implemented scheme.
