“…Estimation of the costs of the PHS system according to the empirical formulas given in [19,28] can be used only for the first evaluation of pre-feasibility studies and grading of similar projects, as a more detailed analysis should be employed for each proposed PHS system in the same group of used technology. The disadvantage of using empirical formulas proposed for new installations of overall PHS system for calculations of different options within one particular system can be seen in Table 6, where costs of the grid connection have been calculated differently for the units with the same size of pumps and PHTs.…”

h i g h l i g h t s" The most widespread storage in power systems is the pumped/reversible hydro storage. " The electricity market does not adequately rewarded all services that PHS provide to the electricity system. " The FIT-GO varies in the range of 42-265 €/MW h for an average capacity factor of 20%. a r t i c l e i n f o t r a c tThis paper analyses potential supporting schemes for pumped hydro storage (PHS) facilities in Croatia, which would guarantee recovery of the investment cost, with feed-in tariffs -for instance -which would guarantee payment for discharging wind-originated power as a reward for boosting the integration of renewable energy sources (RESs). The payment level acts as a floor basis for the PHS operator during the decision-making process to contract fixed payments for wind support or to act market-free on other market segments, through price arbitrage and reserve provision. The market share required for the efficient operation of a PHS facility and the levels of feed-in tariff (FIT) are set mathematically. Main findings put the level of FIT for an applied project in Croatia in the range 42-265 €/MW h for an average load factor of 20%, depending on particular local conditions, such as the level of wind power curtailment in the system, the power price for charging the storage and the number of pumps and penstocks, which could lower the capital cost. It is claimed that not all services that PHS provides to the electricity system are adequately rewarded by the electricity market, and thus there is a serious uncertainty as to how investment costs in energy storage would be recovered. Other elements, outside the market, are likely to influence the operation of PHS, such as the regulated level of a desirable rate of curtailment of RES power excess, the adequate level of energy security and the reserve margins which PHS could help to ensure.

“…Many of the presented projects and studies have been directed towards utilization of wind power in isolated systems and the use of pumped storage systems to increase the annual share of the energy supply that can be covered by the wind turbines (Bakos, 2002;Bueno & Carta, 2006;Bueno & Carta, 2005 a and b;Ceralis & Zervos, 2007;Chen et al, 2007;Katsaprakakis et al, 2007;Katsaprakakis et al, 2008;Protopapas & Papathanassiou, 2006;Protopapas & Papathanassiou, 2004). Most small and isolated power systems on islands and in remote areas have been based on diesel generator sets, and many of the proposed hybrid systems are intended for substituting the fossil fuels needed for the existing power supply by renewable energy sources (Bakos, 2002;Bueno & Carta, 2006;Jensen, 2000).…”

“…In recent years, with the increasing integration of the renewable sources, pumped-storage plays an important role in keeping the security of power system by balancing the variations of renewable sources. It is used to balance renewable sources variations for islanded grids in [8][9][10]. The detailed mathematical model combing wind power and pumped-storage has been proposed in [8,9], and the operation strategy for hybrid wind-pumped storage has been investigated in [10].…”

Growing penetration of wind power challenges to power system security, since the conventional generators may not have sufficient capacity to compensate wind power fluctuation plus the reverse peak regulation. In this paper, the high-capacity pumped-storage and fast-response battery-storage are coordinated to compensate the variation of both wind power and load, aiming at shifting peak load, responding to wind power ramping, reducing the curtailment of wind and stabilizing the output of thermal units. A practical framework is designed for optimizing the operation of the hybrid system consisting of the wind, pumped-storage, and battery storage, which can take full advantages of pumped-storage and battery-storage. The detailed mathematical formulations of the pumpedstorage and battery-storage are built. Three cases are studied to demonstrate the advantages of the proposed coordination method.
