单独的太阳能或单独的风力发电系统的间歇性特性使得独立的可再生能源系统在没有合适的储能能力的情况下无法完全可靠。在本研究中，引入了最传统、最成熟的存储技术——抽水蓄能（PHS）来支持独立微电网太阳能-风能混合系统。本文探索了一种新的解决方案来应对能源存储这一具有挑战性的任务。建立了混合系统的数学模型并介绍了工作原理。所提出的系统应用于为香港一个偏远岛屿供电的案例研究，并对其技术可行性进行了检验。逐小时模拟结果表明，可通过引入PHS技术来补偿可再生能源的间歇性。因此，可以提供可靠且环保的电源。结果表明，从技术上讲，基于 PHS 的可再生能源系统是实现偏远社区 100% 能源自主的理想解决方案。
The intermittent characteristic of a solar-alone or a wind-alone power generation system prevents the standalone renewable energy system from being fully reliable without suitable energy storage capability. In this study, the most traditional and mature storage technology, pumped hydro storage (PHS), is introduced to support the standalone microgrid hybrid solar-wind system. This paper explores a new solution for the challenging task about energy storage. A mathematical model of the hybrid system is developed and the operating principle is introduced. The proposed system is applied in a case study to power a remote island in Hong Kong, and its technical feasibility is then examined. The hour-by-hour simulation results indicate that the intermittent nature of the renewables can be compensated by introducing the PHS technology. Therefore, a reliable and environmentally friendly power supply can be provided. The results demonstrate that technically the PHS based renewable energy system is an ideal solution to achieve 100% energy autonomy in remote communities.
