“…Likewise, studies have been undertaken with similar goals for Malta [12], Lesbos [13] or Salina [14]. It should be noted that this problem has also been tackled using other approaches, including the use of a geographic information system (GIS) to identify the renewable potential in small islands [15], the use of an imaginary island to highlight the strengths of various renewable integration techniques [16] or the proposal for a design and sizing method of hybrid power plants in autonomous insular power systems for the maximization of renewable energy sources (RES) penetration [17]. Nevertheless, all these studies undertaken to date tackle the problem of the maximisation of renewable penetration on islands by focussing in particular on one of the sectors that form part of the energy system, usually on the electricity sector.…”

“…In those authors' opinions, such a hybrid energy sources does not have to provide power all the time and its use can be limited to specific periods in order to facilitate the operation of other energy sources. Two more papers [14,15] investigated the WT-PSH concept on Ikaria Island (the Aegean Sea). Similarly, as in our research, the authors of the aforementioned papers have assumed that the available energy from the WT will first be pumped into the upper reservoir and then dispatched when needed.…”

Variable renewable energy sources (VRES), such as solarphotovoltaic (PV) and wind turbines (WT), are starting to play a significant role in several energy systems around the globe. To overcome the problem of their non-dispatchable and stochastic nature, several approaches have been proposed so far. This paper describes a novel mathematical model for scheduling the operation of a wind-powered pumped-storage hydroelectricity (PSH) hybrid for 25 to 48 h ahead. The model is based on mathematical programming and wind speed forecasts for the next 1 to 24 h, along with predicted upper reservoir occupancy for the 24th hour ahead. The results indicate that by coupling a 2-MW conventional wind turbine with a PSH of energy storing capacity equal to 54 MWh it is possible to significantly reduce the intraday energy generation coefficient of variation from 31% for pure wind turbine to 1.15% for a wind-powered PSH The scheduling errors calculated based on mean absolute percentage error (MAPE) are significantly smaller for such a coupling than those seen for wind generation forecasts, at 2.39% and 27%, respectively. This is even stronger emphasized by the fact that, those for wind generation were calculated for forecasts made for the next 1 to 24 h, while those for scheduled generation were calculated for forecasts made for the next 25 to 48 h. The results clearly show that the proposed scheduling approach ensures the high reliability of the WT-PSH energy source.

“…Katsaprakakis [6] reviews the design and dimensioning of hybrid power plants in autonomous insular power systems of different sizes in Greece, with different technologies for energy generation and storage. The optimization of the dimensioning of the examined hybrid power plants is usually based on either the maximization of the RES penetration or on the optimization of economic indices of the required investments [6].…”

h i g h l i g h t sOperational strategy and sizing optimization of an integrated power and water supply system. Multiobjective optimization using the Direct Multisearch method. Significant increase in RES production of total electricity production is feasible. Significant cost and CO 2 emissions reductions are achievable. a b s t r a c tThe penetration of intermittent renewable energy sources, for instances wind power, in the power system of isolated islands is limited, even when there is large potential. The wind power that cannot be directly injected in the power grid is usually curtailed. In addition, some islands need to desalinate seawater to produce fresh water, increasing the pressure on the power system, because desalination needs electricity. Nevertheless, the water scarcity problem of an island can be part of the solution of the problem of its integration of intermittent renewable energy sources. To tackle this issue, a system was proposed to use the excess wind power in desalination units and in a pumped hydro storage, resulting in an integrated power and water supply system that would minimize the wind power curtailed. This paper proposes a methodology to optimize the size and operational strategy of this wind powered desalination and pumped hydro storage system. The objective is to minimize the total annualized production costs, maximize the percentage of renewable energy sources in the total power production and minimize the wind power curtailed. To solve this optimization problem, a derivative free multiobjective optimization method (Direct MultiSearch) is used. This methodology is applied to the integrated power and water supply system proposed for the island of S. Vicente, in Cape Verde. The results show that the penetration of renewable energy sources can reach 84% with a 27% decrease of power and water production costs and 67% decrease of CO 2 emissions, in relation to the values foreseen for 2020.
