“…The undesirable impacts of high percentages of PV integration call for the study to determine the circuit's PV hosting capacity [13][14][15][16][17][18][19][20][21][22][23]. Given a large number of potential PV deployment scenarios, researchers have primarily looked into simulation-based frameworks [13][14][15][16][17][18][19][20][21][22].…”

Abstract:The widespread integration of photovoltaic (PV) units may result in a number of operational issues for the utility distribution system. The advances in smart-grid technologies with better communication and control capabilities may help to mitigate these challenges. The objective of this paper is to evaluate multiple voltage control methods and compare their effectiveness in mitigating the impacts of high levels of PV penetrations on distribution system voltages. A Monte Carlo based stochastic analysis framework is used to evaluate the impacts of PV integration, with and without voltage control. Both snapshot power flow and time-series analysis are conducted for the feeder with varying levels of PV penetrations. The methods are compared for their impacts on (1) the feeder's PV hosting capacity; (2) the number of voltage violations and the magnitude of the largest bus voltage; (3) the net reactive power demand from the substation; and (4) the number of switching operations of feeder's legacy voltage support devices i.e., capacitor banks and load tap changers (LTCs). The simulation results show that voltage control help in mitigating overvoltage concerns and increasing the feeder's hosting capacity. Although, the legacy control solves the voltage concerns for primary feeders, a smart inverter control is required to mitigate both primary and secondary feeder voltage regulation issues. The smart inverter control, however, increases the feeder's reactive power demand and the number of LTC and capacitor switching operations. For the 34.5-kV test circuit, it is observed that the reactive power demand increases from 0 to 6.8 MVAR on enabling Volt-VAR control for PV inverters. The total number of capacitor and LTC operations over a 1-year period also increases from 455 operations to 1991 operations with Volt-VAR control mode. It is also demonstrated that by simply changing the control mode of capacitor banks, a significant reduction in the unnecessary switching operations for the capacitor banks is observed.

В качестве варианта решения проблемы корректной настройки РЗ, обеспечивающей её правильное функционирование в современных ЭЭС, предлагаются алгоритмы, например [6,7], определения объема и мест установки ВИЭ таким образом, чтобы это не влияло на настройки РЗ и соответственно на их работу. Такой подход исключает необходимость существенного обновления существующих методов расчета уставок, однако сдерживает внедрение ВИЭ.…”

“…It can be done by developing special algorithms to determine the capacity and installation location of the new generating units, so that their penetration is not affected on SCC levels and, accordingly, relay protection, and automation operation. [15][16][17] In this regard, the improvement of adequacy of SCC calculations is an extremely important task, particularly as, according to the statistic, short circuit (SC) is one of the most frequent and dangerous accidents in EPS, which can cause blackouts. 18,19 The rest of the paper is organized as follows.…”

Summary Reliability and efficiency of electric power systems (EPS) operation depend on the adequacy of information about quasi‐state and transient processes in EPS used for their research, design, and operation. A value of short‐circuit currents (SCC), especially their maximum values, is one of the important information used for different tasks. The difficulty of obtaining this information is the need to use a large‐scale EPS mathematical model for SCC calculation. The total mathematical model of any large‐scale EPS is a stiff and nonlinear system of differential equations of high order. Such system cannot be solved analytically. Satisfactory solution is also impossible by using the numerical approach that leads to the need for applying simplifications and limitations reducing the adequacy of simulation results. Therefore, each solution should be validated. The comparison of simulation results with the field data is the most reliable way of validation. However, the acceptable amount of field data cannot be obtained in the foreseeable future in view of the obvious variety of EPS modes, especially emergency ones. An alternative way of validation is suggested in the paper: the using of an adequate reference model instead of field data. The experimental sample of hybrid real‐time power system simulator having the necessary properties and capabilities is used as the reference model. The indicated possibility of SCC calculation validation is proved by the experimental studies shown in the paper.
