“…Therefore, energy storage systems such as batteries are accompanying wind turbines (WT) and photovoltaic units (PVs) to overcome the rapid and frequent intermittency of their output powers [9]. The application of battery energy storage (BES) systems facilitates a consistent power generation by renewables and a steady supply of electricity to the users [10][11][12]. Combining the suitable energy resources along with defining their ratings and operation strategies have been the focus of recent research, and different new techniques have been proposed in the literature to enhance the performance of such systems by proper placement and planning while minimizing the cost of the distribution network and satisfying system technical constraints [13].…”

The main focus of this paper is to select an economically suitable sustainable standalone power supply system for a remote off-grid town in Western Australia. Existing power systems of such remote towns in Australia have adverse environmental impacts and contribute to global warming due to the utilization of fossil fuels, especially diesel and gas. The possible electricity supply systems for such towns can vary from a diesel/gas generator towards a hybrid system composed of a generator, wind turbine, photovoltaic system, and battery energy storage. In order to limit the cost of the system and to propose the most economically feasible solution, various combinations of supply systems are considered. These systems are analyzed in this paper by the help of HOMER software to determine the optimal architecture and the control strategy of the supply system. This study has used real demand data of the town, as well as the prices of different electrical components in the Australian market. The scenario which yields the minimum cost of energy is defined and suggested. Also, a decision-making based technique is proposed to help the local electricity utility in finding the suitable solution in the case of budget limits on the investment and annual operation and maintenance. Another aim of this analysis is to investigate and illustrate the impact of a small annual load growth on the size of the selected components for the selected power system, as well as the total net present cost and the cost of electricity. A sensitivity analysis is also performed to analyze the impact of uncertainties of some of the parameters in the outcome of the study to obtain the optimized cost of the selected system.

“…Reference [28] reports that the contribution of residential rooftop PVs in Australia is around 43% of total PV generation which can enhance the ability of voltage regulation in local regions. References [29]- [31] propose an integrated PV, energy storage (ES) and PEV system for self-feeding of houses.…”

The worldwide acceptance of plug-in electric vehicles (PEVs) is expected to tremendously grow in the next few years. Uncoordinated PEV charging can cause serious grid issues such as overloading of transformers and unacceptable voltage drops. Single-phase residential charging can also initiate or contribute to voltage unbalance in distribution networks. A potential solution for the PEV integration is shifting the charging activities from peak to valley periods. Therefore, this paper firstly investigates the impacts of uncoordinated single-phase PEV charging at residential houses on three-phase distribution networks. Then, it proposes a novel PEV charging coordination strategy based on heuristic genetic algorithm (GA) to perform online centralized charging considering transformer loading and bus voltage profiles. Based on this, a decentralized PEV reactive power discharging approach is presented where the reactive power is discharged at selected nodes for further reduction of voltage unbalance. The impacts of uncoordinated PEV charging as well as the performance of the proposed centralized PEV charging and decentralized var discharging strategies are tested on a real unbalanced Western Australian distribution network under the Perth Solar City project over 24 hours. INDEX TERMS Centralized PEV charging, decentralized PEV var discharging, voltage unbalance and distribution network.

“…As a consequence, in order to not compromise reliability and quality of the supply, modern power systems have now to become "smarter", for properly managing power received both from centralized and distributed sources; of course, this could be accomplished by means of sophisticated control and communication technologies but, undoubtedly, also energy-storage systems can have a central role [1][2][3][4][5][6][7][8][9][10][11][12][13][14].…”

Energy storage is undoubtedly a crucial aspect for the optimal managing of modern active distribution systems. In this paper, a smart utilization of batteries within grid-connected PV-plants is introduced and discussed. Batteries are utilized for maximizing the power generation of a PV-field operating under partial shading conditions, also obtaining the conventional energy storage task. In fact, batteries are proposed to be utilized in a distributed framework together with simple boost-type DC-DC converters; by this way, the power generated by a PV-field can be maximized also in presence of significant mismatches among different PV-modules connected in series, attaining some important advantages with respect to both conventional PV-plants with a centralized energy storage system or to conventional distributed Maximum Power Point Tracking (MPPT) systems with no batteries. Experimental and numerical data are presented, analyzed and discussed.
