“…In a report, it is stated that for European islands more than %15 of all imports are energy imports that can be reduced by RES integration [3]. However, the intermittency of RES is especially a core concern for small grid structures such as insular areas [5]. Thus, the major concern for increasing RES penetration is the stability of the grid in terms of frequency and voltage control, reactive power supply, etc.)…”

Insular electricity grids are considered to have a more fragile structure than the mainland ones due to several factors such as the lower inertia because of lower number of generation facilities connected to the system, absence or insufficient interconnection with the main grid, etc. The recent trend of integrating large portions of environmentally sustainable power generation units that have a significantly volatile nature in the generation mix (such as wind and solar energy conversion systems) within this fragile structure, poses profound challenges that need deeper and specific analysis. This study aims to provide an overview of insular power system structures and operational requirements, especially under increasing penetration of renewable energy sources. Firstly, a general evaluation of insular power systems is presented. Then, potential challenges are thoroughly discussed together with opportunities to tackle them. Future technological developments, as well as innovative applications are also given special attention. Hence, this paper contributes to the scarce literature regarding insular power systems by providing a critical overview of issues regarding their operation and possible solutions.

“…The RenewIslands method has been developed for energy planning of isolated islands [27] and has been implemented into the H2RES software [11,28]. Its core concept is to use heuristic rules to evaluate and structure information on local resources and demands, select promising renewable technologies and devise possible energy systems.…”

h i g h l i g h t sA hybrid synthesis method for renewable energy systems is presented. Heuristic equipment preselection is combined with superstructure-based optimization. A real world case study is analyzed (Mljet Island, Croatia). Investment cost savings of up to 59% compared to classical simulation are achieved. The computational effort required for optimization is low. a r t i c l e i n f o t r a c tAn efficient synthesis method for renewable energy systems is presented that exploits synergies between heuristic-and optimization-based approaches. For this purpose, the RenewIslands method has been integrated into a superstructure-based optimization approach. The resulting hybrid approach consists of two steps: First, heuristic-based equipment preselection identifies a set of promising candidate technologies. Next, the preselected technologies are employed in superstructure-based optimization to determine the optimal renewable energy system. The heuristic preselection systematically avoids excessively large superstructures, while the subsequent optimization ensures that the optimal solution is selected. The proposed method is applied to the case of Mljet Island, Croatia. A renewable energy system is synthesized that requires 59% less investment costs compared to the solution derived by classical simulation. At the same time, the optimization problem is solved in less than 2 min. The proposed hybrid method is shown to provide an efficient route to the synthesis of renewable energy systems.

“…Smart microgrids are understood as the enabling technology, integrating hybrid energy systems and energy storage, which allows for the development and integration of alternative energy sources (see [19], [20], [21], [22], [23], [24], [25] and [26]). It is en essence a micro generation system that uses bidirectional communication systems.…”

“…It is en essence a micro generation system that uses bidirectional communication systems. The concept of smart microgrid for a group of homes can be utilized to define a diverse group of applications, which fosters the ability to monitor and control an electricity network (US Department of Energy, 2010) (see [19], [20], [21], [22], [23], [24], [25] and [26]). There is however not one but several definitions of smart grid, even though it is easily distinguished from a conventional power grid.…”

Abstract:According to seismologists Chile has yet to face another big earthquake in the very near future, yet the country remains largely unprepared against massive electric power systems brake-down. The problem lies in the centralized electric power systems and the lack of adequate technologies and back-up/emergency power systems for disaster recovery. The flaws that are built into the very fabric of the presently centralized power systems were on full display in the February 27th earthquake in Chile. Nowhere it becomes more evident that hugely centralized power generation and distribution systems are extremely vulnerable and ineffective to disruptions from natural disasters, human error or other calamities. The large power networks that once proved very efficient and secure, are now at the center of discussion fueling the need for decentralization and the rapid growth of distributed generation (DG). Highly decentralized, diversified and DG-oriented energy matrix is notoriously much better suited to withstand these disasters. In centralized electric power grids, servicing large metropolitan areas, albeit with some but limited differentiation in service, can only be on or off, so either everyone gets power or no one does. This makes recovering power service in an emergency situation a much more difficult task. On the other hand, decentralized power systems (DPS) reduce the obstacles to disaster preparation and recovery by allowing the focus to shift first to critical infrastructure and then to flow outward to less integrated outlets. A DG-based model for a smart micro-grid based on hybrid electric power systems (HEPS) using both renewable energy technologies (RET) and conventional power generation units is presented. The hybrid energy system may be portable or fixed in one place, highly reliable, easy to assemble, modular, flexible and cost-effective solution, that is ready-to-run and go to where it is needed to supply power in natural disaster.
