This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.

“…A considerable contributing factor in these losses is the excessive reactive power demand at the distribution level, which negatively impacts the voltage profile of the system [2]. To protect the significant amount of power from wastage in the form of electrical losses, various methods, including Synchronous Condenser (SC) [3], Distribution Generation (DG) [4], FACTS devices [5], and capacitor placement [2], have been widely studied.…”

The passive power distribution networks are prone to imperfect voltage profile and higher power losses, especially at the far end of long feeders. The capacitor placement is studied in this article using a novel Mine Blast Algorithm (MBA). The voltage profile improvement and reduction in the net annual cost are also considered along with minimizing the power loss. The optimization problem is formulated and solved in two steps. Firstly, the Voltage Stability Index (VSI) is used to rank the nodes for placement of the capacitors. Secondly, from the priority list of nodes in the previous step, the MBA is utilized to provide the optimal location and sizes of the capacitors ensuring loss minimization, voltage profile improvement, and reduced net annual cost. Finally, the results are tested on 33 and 69 radial node systems in MATLAB. The results for the considered variables are presented which show a significant improvement in active and reactive power loss reduction and voltage profile with lesser reactive power injection.

“…Various methods are used for injecting reactive power in distribution system for reducing power losses, including the method of capacitor placement [3], distribution generator (DG) [4], FACT devices [5], and synchronous condenser (SC) [6]. The SC is a conventional and well-established method for power loss compensation.…”

“…In recent years, (DGs) have been widely preferred, as they could (i) minimize power losses; (ii) improve the voltage profile; and (iii) due to the green onsite generation. Due to the fact that the conventional power system is designed for unidirectional power flow, additional care must be taken in order to avoid reverse power flow [5]. Using (FACTs) devices, power flow and oscillation damping can be controlled.…”

Annual Cost and Loss Minimization in a Radial Distribution Network by Capacitor Allocation Using PSO

et al. 2021

Increasing power demand from passive distribution networks has led to deteriorated voltage profiles and increased line flows. This has increased the annual operations and installation costs due to unavoidable reinforcement equipment. This work proposes the reduction in annual costs by optimal placement of capacitors used to alleviate power loss in radial distribution networks (RDNs). The optimization objective function is formulated for the reduction in operation costs by (i) reducing the active and reactive power losses, and (ii) the cost and installation of capacitors, necessary to provide the reactive power support and maintain the voltage profile. Initially, the network buses are ranked according to two loss sensitivity indices (LSIs), i.e., active loss sensitivity with respect to node voltage (LSI1) and reactive power injection (LSI2). The sorted bus list is then fed to the particle swarm optimization (PSO) for solving the objective function. The efficacy of the proposed work is tested on different IEEE standard networks (34 and 85 nodes) for different use cases and load conditions. In use case 1, the values finalized by the algorithm are selected without considering their market availability, whereas in use case 2, market-available capacitor sizes close to the optimal solution are selected. Furthermore, the static and seasonal load profiles are considered. The results are compared with recent methods and have shown significant improvement in terms of annual cost, losses and line flows reduction, and voltage profile.
