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

Abstract. The issues of modern urban development raise a significant question about an environmental cleanliness of progressing cities. Energy sources which are running on fuel cause tremendous harm to the atmosphere. Therefore, special attention is paid to the rational use of natural renewable resources such as wind and solar energy. Wind-electric sets, or wind turbines, are able to work autonomously, which is also important for the development of modern "smart" cities. Currently, the most commonly used design of wind turbines is the system which has the form of a tower of circular cross section (also called pipe), which carries at the upper end a nacelle with wind wheel. When such a system is being designed in urban conditions the wind pulsation and seismic calculations are added to the standard calculations. These added calculations are dynamic loads. It is known that in the process of solution of dynamic tasks design models of various levels of approximation can be used. It occurs due to stages of the design and other factors. The question of errors, which are associated with the use of a dissected, or partitioned, design scheme, raises.
