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.

This paper presents a new approach for modelling energy flows in complex energy systems with parallel supply of fresh water and electricity. Such systems consist of renewable energy sources (RES), desalination plant, conventional power plants and the residual brine storage which is used as energy storage. The presented method is treating energy vectors in the system as control variables to provide the optimal solution in terms of the lowest critical excess of electricity production (CEEP) and h ighest possible share of RES in the supply mix. The optimal solution for supplying the demands for fresh water and electricity is always found within the framework of model constraints which are derived from the physical limitations of the system. The presented method enables the optimization of energy flows for a larger period of time. This increases the role of energy storage when higher integration of RES in the supply mix. The method is tested on a hypothetical case of Jordan for different levels of ins talled wind and PV capacities, as well as different sizes of the brine storage. Results show that increasing the optimization horizon from one hour to 24 hours can reduce the CEEP by 80% and allow the increase of RES in the supply mix by more than 5% without violating the CEEP threshold limit of 5%. The activity of the energy (brine) storage is crucial for achieving this goal. * Corresponding author; email: luka.perkovic@fsb.hr; tel. +385 1 6168494 KeywordsOptimal energy flows; renewable energy sources (RES); desalination plant; energy storage; critical excess of electricity production (CEEP) Research highlights a new methodology for optimal management of energy systems is proposed  critical excess of electricity production is reduced by optimizing the energy flows  at the same time, the curtailment from the RES can be decreased Nomenclature

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
