Due to the promoted integration of renewable sources, a further growth of strongly transient, distributed generation is expected. Thus, the existing electrical grid may reach its physical limits. To counteract this, and to fully exploit the viable potential of renewables, grid-balancing measures are crucial. In this work, battery storage systems are embedded in a grid simulation to evaluate their potential for grid balancing. The overall setup is based on a real, low-voltage distribution grid topology, real smart meter household load profiles, and real photovoltaics load data. An autonomous optimization routine, driven by a one-way communicated incentive, determines the prospective battery operation mode. Different battery positions and incentives are compared to evaluate their impact. The configurations incorporate a baseline simulation without storage, a single, central battery storage or multiple, distributed battery storages which together have the same power and capacity. The incentives address either market conditions, grid balancing, optimal photovoltaic utilization, load shifting, or self-consumption. Simulations show that grid-balancing incentives result in lowest peak-to-average power ratios, while maintaining negligible voltage changes in comparison to a reference case. Incentives reflecting market conditions for electricity generation, such as real-time pricing, negatively influence the power quality, especially with respect to the peak-to-average power ratio. A central, feed-in-tied storage performs better in terms of minimizing the voltage drop/rise and shows lower distribution losses, while distributed storages attached at nodes with electricity generation by photovoltaics achieve lower peak-to-average power ratios.

“…It is necessary to select an island energy storage form through technical and economic analysis. In [12], the life cycle cost of a microgrid with different energy storage schemes (including battery storage, seawater pumped storage and hybrid energy storage systems) is analyzed under the condition of a given island microgrid with the necessary energy storage requirements. The results show that, in most cases, the cost of the pumped storage scheme is lower than that of the battery storage scheme, and the cost difference is related to factors such as the demand for energy storage and the rate of return on the investment of the assets.…”

Currently, small islands are facing an energy supply shortage, which has led to considerable concern. Establishing an island microgrid is a relatively good solution to the problem. However, high investment costs restrict its application. In this paper, micro pumped storage (MPS) is used as an energy storage system (ESS) for islands with good geographical conditions, and deferrable appliance is treated as the virtual power source which can be used in the planning and operational processes. Household acceptance of demand response (DR) is indicated by the demand response participation degree (DRPD), and a sizing optimization model for considering the demand response of household appliances in an island microgrid is proposed. The particle swarm optimization (PSO) is used to obtain the optimal sizing of all major devices. In addition, the battery storage (BS) scheme is used as the control group. The results of case studies demonstrate that the proposed method is effective, and the DR of deferrable appliances and the application of MPS can significantly reduce island microgrid investment. Sensitivity analysis on the total load of the island and the water head of the MPS are conducted.

“…Another continental study has been conducted for Denmark [32], where wind generation plays a crucial role in covering energy demand -in the present paper authors pointed to the fact that wind speed variation on a short time scale does not have a meaningful impact on PSH operation. References [33][34][35] analyzed the PV-TW-PSH hybrid from the technical and economical perspective in the case of Greek islands and an island located near Hong Kong. Results indicate that wind and solar power energy sources can be a reliable and cost effective energy source.…”

Abstract. This paper introduces a mixed integer non-linear mathematical model for a simulation of a hybrid energy source consisting of photovoltaics (PV), wind turbines (WT) and pumped storage hydroelectricity (PSH). The concept of PV-WT-PSH has been well described and evaluated for sparsely populated or remote areas such as islands. Here, due to the rapid development of renewable energy sources and most importantly the variable (non-dispatchable) energy sources such as wind and solar, the idea of wind and solar powered PSHs has been investigated in the context of the national energy system. The economic and environmental impact of the proposed hybrid has been assessed. The results reveal that to cover almost 40% of the energy demand one should expect the energy cost to increase by 25%. Due to the usually limited natural resources available for island communities and the need to transport goods (such as oil or coal) from the continent (which increases their cost) and often very favorable solar and wind conditions, RES could easily compete economically with conventional power sources. But one would have to overcome the same problems which we face nowadays with the integration of RES, namely, their variable and non-dispatchable nature. As has already been mentioned, several approaches [8][9][10][11][12][13][14][15][16][17][18][19][20] can be applied, but the concept which incorporates at least three of them is a hybrid of photovoltaic (solar power), wind turbine and pumped storage hydroelectricity (PV-WT-PSH).Coupled wind and solar power sources tend to exhibit lower variability and it is well known that on an annual time scale they exhibit a strong complementarity [11,12,[21][22][23][24]. The concept of the temporal complementarity of a dual energy source can be explained by means of two sine functions which depict their variation in energy output; in the case of perfect temporal complementarity they will be out of phase with each other by π/2, or in other words they have a very strong (˗1) negative correlation. However, perfect complementarity is very unlikely, and on a shorter time scale (days, hours) it is almost non-existent. In consequence, periods will occur with no energy available from either wind or solar generation. The opposite may occur when both sources simultaneously generate energy at their nameplate capacity. In general, the ambitious goal of meeting demand purely using VRES would require the whole system to be oversized, which will intrinsically lead to significant energy surpluses.Therefore there arises a need to somehow transfer the energy in time, meaning that surpluses occurring in period t might be used in period t + x. This can be done by means of energy storage. The most mature (and practically the only) bulk energy storage technology is PSH, which uses the elevation difference between an upper and a lower reservoir to store excess energy and release it when the generation from WT and PV is not sufficient to cover demand. It is important to note that in the
