“…The individual phase tap control of OLTC based on proportional control proposed in [19] instead increases the voltage unbalance. In [20], the sensitivity-based individual phase reactive power control of energy storage system (ESS) improves voltage magnitude unbalance defined by IEEE, but it is not easy to extend it to consider voltage angle unbalance. Hence, an optimization-based approach is suitable for voltage regulation considering multiple voltage unbalance metrics.…”

“…Hence, an optimization-based approach is suitable for voltage regulation considering multiple voltage unbalance metrics. Furthermore, most of the existing approaches (e.g., [3,5,15,16,20]) use end-user equipment such as PV inverters, EVs, capacitors, and ESS. Hence, the methods introduce some issues such as dependency on the equipment's capacity, and incentives or fairness to control owners' equipment.…”

Penetration of equipment such as photovoltaic power generations (PV), heat pump water heaters (HP), and electric vehicles (EV) introduces voltage unbalance issues in distribution systems. Controlling PV and energy storage system (ESS) outputs or coordinated EV charging are investigated for voltage unbalance compensation. However, some issues exist, such as dependency on installed capacity and fairness among consumers. Therefore, the ideal way to mitigate unbalanced voltages is to use grid-side equipment mainly. This paper proposes a voltage unbalance compensation based on optimal tap operation scheduling of three-phase individual controlled step voltage regulators (3φSVR) and load ratio control transformer (LRT). In the formulation of the optimization problem, multiple voltage unbalance metrics are comprehensively included. In addition, voltage deviations, network losses, and coordinated tap operations, which are typical issues in distribution systems, are considered. In order to investigate the mutual influence among voltage unbalance and other typical issues, various optimization problems are formulated, and then they are compared by numerical simulations. The results show that the proper operation of 3φSVRs and LRT effectively mitigates voltage unbalance. Furthermore, the results also show that voltage unbalances and other typical issues can be improved simultaneously with appropriate formulations.

“…Furthermore, a smart inverter improves the voltage unbalance index and detects the unbalanced state of voltage magnitude and phase [12] using energy storage systems (ESSs) [13,14]. A sensitivity-based voltage control strategy is developed for the energy storage system in [15]. ESSs are used for this purpose, which include a superconducting magnetic energy storage (SMES) unit [16,17], a flywheel [18,19], or batteries [20].…”

This paper presents an effective solution to overcome the problem caused by intermittent energy sources that are connected to a balanced/unbalanced distribution system using a superconducting magnetic energy storage (SMES) system by mitigating the voltage and frequency fluctuations during wind gusts. The fuzzy logic control technique (FLC) is used with SMES to improve the voltage and frequency. A squirrel cage induction generator (SCIG) is applied as the wind energy generator. The IEEE 33-bus distribution system is used to validate the proposed method. Buses 18 33 are the weakest points in this system; thus, the wind and SMES systems are connected to the system at these buses. We used MATLAB/Simulink to simulate the performance of the IEEE 33-bus system (balanced/unbalanced) considering the SMES, wind system, and fuzzy logic control (FLC). The simulation results show the high performance of the proposed control method to alleviate the voltage and frequency fluctuation and achieve the power leveling strategy of the studied system.
