“…Every optimization technique has their own limitations as given in Table 4, so it can be concluded that hybrid optimization techniques may overcome these limitations by combining their strengths, which results in more accurate and optimal solutions to practical engineering problems. 148 A new voltage stability index for online monitoring and load shedding is proposed in another study. Moreover, an improved algorithm for optimal load shedding with voltage stability as constraint presented in a previous study.…”

Summary A blackout is usually the result of increasing load beyond the transmission capacity of the power system. One of the main reasons for power blackouts is voltage collapse. To avoid this problem, the proper corrective measures called load shedding is required. In critical and extreme emergencies, under voltage load shedding (UVLS) is performed as a final remedy to avoid a larger scale voltage collapse. Therefore, UVLS is considered state of the art to achieve voltage stability. This review summarizes and updates the important aspects of UVLS; it also provides principle understanding of UVLS, which are critical in planning such defense schemes. Moreover, this article provides a discussion on recent state‐of‐art UVLS schemes applied in various power industries. Additionally, the pros and cons of the conventional and computational intelligence techniques are discussed. It is envisioned that this work will serve as one‐stop information for power system engineers, designers, and researches.

“…It was highlighted in [18] that the output power of photovoltaic and wind generation might change during the UFLS period, thus the power generation variations during the UFLS were considered. In [19], the authors proposed an improved UFLS in the islanded distribution network with high penetration of solar photovoltaic generation. Also, the approach of [20] focused on the effects of high photovoltaic penetration on the distributed system, but all of the simulations were carried out in the distributed grid.…”

Abstract:As the requirements of economical operation and reliability on power grid are enhanced gradually nowadays, the existing under frequency load shedding (UFLS) scheme is not quite fit for the modern power system that integrates high wind power. In this paper, the impacts of high wind power penetration on the UFLS are discussed thoroughly. A novel adaptive load shedding (LS) scheme is presented taking the high wind power penetration into account. In the proposed scheme, the equivalent inertia constant (EIC) is calculated accurately to improve the power deficit accuracy so as to reduce the error of LS. The dynamic correction of power deficit is able to solve the negative effects of the wind power output random reduction/the wind generator tripping. Besides, the locking criterion is capable of avoiding the influences of the wind power output random increase on the LS, thus cutting down the LS costs and even preventing the frequency overshoot. Moreover, in terms of the LS parameters setting, the coordination of the low frequency protection of the wind generator and the frequency threshold is addressed. The location and capacity model of LS, which is based on the load characteristics, can ameliorate the frequency recovery process. Finally, the validity and robustness of the proposed scheme are verified in the simulations on the IEEE-39 bus system with high wind power penetration.

Abstract. This paper evaluates and analyzes the performance of three different types of photovoltaic (PV) arrays connected to utility-grid without any storage system in Malaysia. The three types modules include Poly-Crystalline, Mono-Crystalline and Thin-Film modules, each works separately and are connected to three DC/AC inverters where it monitored and controlled over an IP network system. The system installed and monitored for one-year period and this is the first work describing such systems of different PV types at the same plant in the proposed location. The system continuously collects and stores all data sets of DC/AC current, voltage, frequency and power for a 5-minutes period. Besides, the weather parameters that include ambient temperature, module temperature, solar irradiation and wind speed. The performance of this plant is evaluated by analyzing the collected data sets and then applying performance indices such as final energy output, array yield, final yield, reference yield, system efficiency and performance ratio. The results show that the PV performance is depending directly on the solar irradiation as well as the surrounding environmental conditions. Also, the results show a very-good efficiency of the proposed modules and demonstrate the potential of using such systems in any area with the similar conditions.
