“…There is a greater call for long‐term grid reinforcement to accommodate high levels of PV generations. One of the key challenges is to make the PV power plants intelligent enough to ride through momentary voltage sags on the grid side, which is different from the anti‐islanding condition [1]. In a low voltage (LV)/medium voltage (MV) distribution network, unbalanced grid faults are more common compared to balanced three‐phase faults.…”

A dynamic voltage support strategy using smart photovoltaic (PV) inverters during unbalanced grid faults events is proposed. It uses Karush-Kuhn-Tucker condition for finding optimal solutions to calculate the inverter's active and reactive current references. The proposed methodology also takes the X/R ratio into consideration which allows the inverter to differentiate weak or strong grid conditions and adjust its reference currents. Existing multiple-complex coefficient-filter based phase locked loop is used to extract the positive and negative sequence components. The proposed strategy deploys existing dual vector current control to ensure optimal current injection and low voltage ride through. A distributed ride-through coordination approach among multiple inverters is also proposed based on different optimisation goals-either fundamental positive or fundamental negative sequence voltage support. The strategy is simulated, and inverter's transient performance is experimentally verified on a modified IEEE-13 bus test feeder using controller hardware-in-the-loop approach. Results show substantial evidence that the proposed method can be successfully applied to support the grid during an unbalanced fault event.

“…The integration of clean energy is accompanied in driving down the cost of these resources such as biomass distributed generation units (BDGs). There are various benefits of installing the distributed generations (DGs) with their several types and characteristics which can be categorized into economic, technical, and environmental benefits 1‐23 . Economically, DG avoids the costs of installing new transmission circuits and power generation plants.…”

Summary The majority of power utilities have targeted pretentious clean and efficient energy plans. These plans are accompanied in driving down the cost of biomass distributed generation units (BDGs). This paper proposes an optimal allocation procedure of BDGs to enhance the performance of the distribution systems and to reduce the related environmental emissions. The proposed procedure aims to maximize the power utilities' benefits in terms of power loss reduction, energy sales excess, and pollutant emission reduction. It also takes into consideration the minimization of the annual operational and maintenance costs of the BDGs. The load growth with several loading levels over the BDGs planning period is presented. For achieving this target, an adaptive equilibrium optimizer (EO) technique is developed which is characterized by simple structure and dynamic control parameters. The proposed procedure is applied to IEEE 33‐bus and practical large‐scale 141‐bus system of AES‐Venezuela in the metropolitan area of Caracas. The simulation results declare the effectiveness and capability of the employed EO technique in achieving great benefits in terms of energy sales and environmental emissions with a high improvement of the voltage profile and minimizing power losses. In addition, a comparative and statistical analysis is executed with several recent techniques to show the superior capability of the proposed procedure using the EO technique.

“…In this context, MICs should be equipped with robust anti-islanding schemes that will facilitate reliable power generation coming from high penetration levels of low-power PV systems. Those techniques are referenced in scientific literature, as communication-based and active techniques [8][9][10][11][12][13]. Communication-based techniques, although fast and free of nondetection zone (NDZ), are subjected to communication failures in the case of low-voltage distribution networks and demand high implementation costs.…”

“…Based on the existing scientific works that resume the active techniques [8][9][10][11][12][13], we can conclude that the emerging topic of robust anti-islanding protection of MICs has not been sufficiently covered by the literature yet. This is because very few of these works refer to the MIC technology, whereas only a limited number of the referenced methods are directly compatible with Pdc-MICs.…”
