“…The PHS has been considered as a large storage system installed more than 95 GW all across the world, generally to promote the wind power integration to supply base load [83]. The need for exploiting PHS unit would be obvious through comparing the local networks demands to corresponding annual wind farm efficiency [81]. A novel strategy is proposed in [51] for self-scheduling (SS) of integrated wind farm and PHS unit.…”

“…The possibility of integrating wind for an isolated electric grid is investigated wherein the operational parameters of PHS system are determined exploiting an integrated calculating algorithm to supply the electric energy on the basis of daily horizon. The most common and the best way to overcome the problems caused by wind power generation in isolated networks are utilizing hybrid hydro/wind schemes [62,[75][76][77][78][79][80][81][82]. That is the most appropriate way to optimally and desirably operate the available wind power capacity with high degree of penetration for small islands with low installed capacity is to use PHS units [62].…”

Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases (GHGs) and also social issues like dramatic increase in global population and increasing energy demand are the main causes of global concerns about energy resource management. In this regard, Renewable Energy Sources (RESs) are the suitable substitution to replace the conventional generating units that emit GHGs due to the use of fossil fuels. Among all RESs, wind energy seems to be promising for generating emission-free electrical energy. However, it is naturally unpredictable due to its intermittency which leads to s ome technical problems such as generation imbalance as well as optimal reserve allocation. This paper investigates the solutions to compensate wind intermittency through introducing various technolo gies such as Pumped-Hydro Storage (PH S) units, Plug-in Hybrid Electric Vehicles (PHEVs), solar energy and other electric storages like batteries. Abstract-Nowadays, the world is encountering severe challenges in the energy generation sector. Environmental issues like climate change, global warming and Green House Gases

“…The use of pumped hydro storage (PHS) for integration in the existing water supply system and increasing the wind penetration from 25% to 70% in the electricity supply of the Corvo island is proposed in [5] and a similar case, but which include sea desalination is given in [6]. The use of PHS for increasing wind penetration in the Lesbos island and algorithm for sizing the PHS units are described in [7,8].…”

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.

“…Case studies and calculations for pumped hydro and hydrogen have in many cases been proposed (Duić and Carvalho, 2004;Caralis and Zervos, 2006;Krajačić et al, 2008;Bueno and Carta, 2006;Kapsali and Kaldellis, 2010) or have been recently implemented, like in Madeira (Empresa de Electricidade da Madeira (EEM), 2010) or are under final construction, like on Ikaria Island in Greece (Public Power Corporation (PPC), 2010).…”

Feed-in tariffs for promotion of energy storage technologies

a b s t r a c tFaster market integration of new energy technologies can be achieved by use of proper support mechanisms that will create favourable market conditions for such technologies. The best examples of support mechanisms presented in the last two decades have been the various schemes for the promotion of renewable energy sources (RES). In the EU, the most successful supporting schemes are feed-in tariffs which have significantly increased utilisation of renewable energy sources in Germany, Spain, Portugal, Denmark and many other EU countries. Despite the successful feed-in tariffs for RES promotion, in many cases RES penetration is limited by power system requirements linked to the intermittency of RES sources and technical capabilities of grids. These problems can be solved by implementation of energy storage technologies like reversible or pumped hydro, hydrogen, batteries or any other technology that can be used for balancing or dump load. In this paper, feed-in tariffs for various energy storage technologies are discussed along with a proposal for their application in more appropriate regions. After successful application on islands and outermost regions, energy storage tariffs should be also applied in mainland power systems. Increased use of energy storage could optimise existing assets on the market.
