“…The generalized Benders decomposition is adopted along with conic programming relaxation in [13] to formulate an optimization problem for eliminating overvoltage by reactive power control. However, as in [9] and [10], knowledge of the grid parameters is required in most optimization-based strategies, complicating implementation in LV networks of different characteristics. A multi-objective genetic algorithm is used in [7] to provide coordinated Volt/VAR control of nd-DERs, increasing the participation in the reactive power support of inverters close to the DST.…”

“…Such features mainly relate to: i) the exploitation of DERs of different natures (i.e., nd-and d-DERs); ii) the implementation of local and coordinated steering of inverters offering ancillary services [5]; iii) the support to enhanced energy exploitation, avoiding APC whenever possible, without implementing complex optimization algorithms; and iv) a generic formulation, which is model-free. In particular, the strategy is suitable for LV radial networks of limited size, comprising a dispatchable PCC with the distribution grid (i.e., as in active distribution networks [9], [13], and LV microgrids [14], [17]).…”

“…Moreover, as found in the literature [4,7], even when dispatchable DERs (e.g., battery-based ESSs (BESSs)) contribute to mitigating overvoltage by implementing conventional Volt/Watt and/or Volt/VAR actions, the DERs' location may affect their participation [7]. As an example, in LV networks with one point-of-common-coupling (PCC) with the distribution grid [4,[8][9][10], the DERs placed close to the distribution system transformer (DST) slightly participate in overvoltage control [7]. Thus, even if such DERs present available power capabilities, they are not exploited [7].…”

“…It is demonstrated that the former approach makes DERs further downstream on the feeder curtail more power than those close to the DST. On the other hand, APC can be equalized [9] among DERs by the latter approach at the expense of higher energy losses. Ref.…”

Large amounts of active power injection by inverter-interfaced distributed energy resources (DER) is a common cause of overvoltage in low-voltage networks. Hence, local active and reactive power control (i.e., Volt/Watt and Volt/VAR, respectively) are adopted to limit voltage rise, leading to active power curtailment. This paper proposes an automatic control strategy to steer non-dispatchable (nd-DER) and dispatchable (d-DER) inverters in low-voltage networks, mitigating overvoltage through local and coordinated Volt/Watt and Volt/VAR functionalities. Active power curtailment is avoided whenever possible. The method does not require i) the implementation of optimization algorithms or ii) knowledge about line impedance parameters or the location of DERs. The control approach exploits the power flow dispatchability of lowvoltage networks comprising one point-of-common coupling with the distribution grid, allowing DERs close to the distribution transformer to also contribute to voltage regulation by only using a low-bandwidth communication link. Simulation results show the flexibilities of the proposed approach and demonstrate that energy exploitation can be increased by up to 25% for the considered scenario in comparison to conventional local Volt/Watt or Volt/VAR schemes. Experimental results based on a laboratory prototype with three inverter-interfaced DERs certify the applicability of the approach to real-life implementations.

“…A real-world APC and Volt/Var control approach has been implemented and demonstrated in [24] in compliance with the standards proposed by the Smart Inverter Working Group. The fairness-based APC methods have been explored in [25,26] with the objective of increasing total PVHC since the location-dependent penalization of active power might often be unfair and overly prohibitive to many households.…”

Photovoltaic (PV) system installation has encouraged to be further expedited to minimize climate change and thus, rooftop solar PV systems have been sparkled in every corner of the world. However, due to technological constraints linked to voltage and currents, the PV hosting capacity has been substantially constrained. Therefore, this paper proposes a competent approach to maximize PV hosting capacity in a low voltage distribution network based on voltage control and dynamic line rating of the cables. Coordinated voltage control is applied with an on-load tap changing transformer, and reactive power compensation and active power curtailment of PV inverters. A case study with probabilistic and deterministic assessments is carried out on a real Sri Lankan network to show how the PV hosting capacity is constrained. The findings revealed the capability of integrated voltage control schemes and dynamic line rating in maximizing hosting capacity. The study is expanded by incorporating the PV rephasing approach in conjunction with the aforementioned control techniques, and the effectiveness of PV-rephasing is clearly demonstrated. When compared to voltage control and conductor static rating, the combined rephasing, voltage control, and DLR yielded a 60% increase in PV hosting capacity.
