“…Utility-sited energy storage provides the needed integration with variable renewable energy sources to mitigate supply-demand imbalances. Previously, pumped hydropower plants had been the only known grid-integrated technology for delivering significant flexibility to the power grid (Beires et al 2018). Common electricity and thermal storage technologies include electrochemical or physical (e.g., compressed air) mediums, ice storage, molten salt storage, and others.…”

Rapid growth in megacities has prompted deep transformations intended to change sociotechnical systems, deep social and institutional practices, and scientific inquiries to better understand energy and material flows of cities. Typically, these processes are defined by sociotechnical experimentation and purposive reshaping of the synergies between jurisdictions, sectors, and technical solutions required to optimize resource management and improve institutional diversity

“…These actions arise from the need for ensuring adequate frequency and voltage regulation, which are traditionally provided by conventional synchronous units. Subsequently, in scenarios of high RES penetration, the operator of the system may give the command of RES curtailment with respect to the operational requirements of conventional units and the spinning reserve criteria [8].…”

Full-Scale Implementation of RES and Storage in an Island Energy System

The field of energy, specifically renewable energy sources (RES), is considered vital for a sustainable society, a fact that is clearly defined by the European Green Deal. It will convert the old, conventional economy into a new, sustainable economy that is environmentally sound, economically viable, and socially responsible. Therefore, there is a need for quick actions by everyone who wants to move toward energy-efficient development and new environmentally friendly behavior. This can be achieved by setting specific guidelines of how to proceed, where to start, and what knowledge is needed to implement such plans and initiatives. This paper seeks to contribute to this very important issue by appraising the ability of full-scale implementation of RES combined with energy storage in an island power system. The Greek island power system of Astypalaia is used as a case study where a battery energy storage system (BESS), along with wind turbines (WTs), is examined to be installed as part of a hybrid power plant (HPP). The simulation’s results showed that the utilization of HPP can significantly increase RES penetration in parallel with remarkable fuel cost savings. Finally, the fast response of BESS can enhance the stability of the system in the case of disturbances.

“…The available literature on HPSs used to be dominated by hydro-pumped storage study cases [7,[10][11][12][13][14], since pumped hydro was perceived to be the most efficient and feasible utility-scale storage solution. The added value of such HPS configurations for island systems is examined in [9,13,14], their dynamic behaviour is the subject of [15][16][17], sizing aspects are investigated in [10,18], while their participation in the market of NII systems is discussed in [9,12].…”

Hybrid power stations (HPSs) are virtual power plants comprising storage and renewable energy source facilities operated in a coordinated manner as dispatchable stations. The HPS concept has been introduced as a means to increase renewable penetration in saturated island systems. The main objective of this study is to shed light on the operation of batterybased HPSs in small-island systems and their investment feasibility. Anticipated benefits for the island system are quantified in terms of system production cost and renewable penetration, while the exploitation of available renewable energy by the HPS is analyzed and the internal operation of its components is evaluated. A mixed integer linear programming generation scheduling approach is used to conduct daily and annual simulations of the entire island generation system, while at the same time optimising the internal management of the HPS as well. Based on the operating results thus obtained, the economic feasibility of battery-based HPS investments using wind, photovoltaics or their combination as the renewable generation component is assessed, by utilising the levelised cost of energy as the primary evaluation index and accounting for the life expectancy of the HPS battery storage system.
