在希腊爱琴海的大多数岛屿上，风能和太阳能的潜力很大，沿着而来的是极高的电力生产成本，这些岛屿包括自治电力网络，这意味着新的可再生能源（RES）投资的紧迫性。为了绕过广泛使用RES产生的电网稳定性限制，调整适当的储能系统（ESS）至关重要。在本分析中，详细研究了在各种自主电网中引入选定的存储技术以确保更高水平的可再生能源渗透率的成本效应，特别是风能和太阳能。系统的参数分析有关的ESS的主要参数对整个装置的经济行为的影响也包括在内。根据所获得的结果，一个适当大小的基于RES的发电站与适当的能量存储设备的合作是一个有前途的解决方案的能源需求问题的许多自主电网现有的世界各地，在同一时间提出了一种清洁能源发电的替代方案，并有助于减少的重要环境问题所造成的操作的热电站。
The high wind and solar potential along with the extremely high electricity production cost met in the majority of Greek Aegean islands comprising autonomous electrical networks, imply the urgency for new renewable energy sources (RES) investments. To by-pass the electrical grid stability constraints arising from an extensive RES utilization, the adaptation of an appropriate energy storage system (ESS) is essential. In the present analysis, the cost effect of introducing selected storage technologies in a large variety of autonomous electrical grids so as to ensure higher levels of RES penetration, in particular wind and solar, is examined in detail. A systematic parametrical analysis concerning the effect of the ESSs’ main parameters on the economic behavior of the entire installation is also included. According to the results obtained, a properly sized RES-based electricity generation station in collaboration with the appropriate energy storage equipment is a promising solution for the energy demand problems of numerous autonomous electrical networks existing worldwide, at the same time suggesting a clean energy generation alternative and contributing to the diminution of the important environmental problems resulting from the operation of thermal power stations.
