Intermittency and unpredictability of variable renewable energy sources, as well as the mismatch between generation and users’ demand, are the major hurdles to overcome looking at 100% renewable grids. Energy storage (ES) technologies are the answer to this question, yet high market costs are still compared to market parity. For the possibility to decouple capacity and power, hence tailoring the energy storage features according to the main functions required, the solutions investigated are based on Vanadium Redox Flow Batteries (VRFBs) and Reversible Solid Oxide Cells (rSOC). In low interconnected micro-grids, the decoupled sizing of capacity and power is an essential feature to attain higher cost-effectiveness.

创新高容量发电储能技术的经济性指向 100% 可再生微电网

可变可再生能源的间歇性和不可预测性，以及发电与用户需求之间的不匹配，是实现 100% 可再生电网需要克服的主要障碍。储能（ES）技术是这个问题的答案，但与市场平价相比，市场成本仍然很高。为了能够解耦容量和功率，从而根据所需的主要功能定制能量存储特性，所研究的解决方案基于钒氧化还原液流电池（VRFB）和可逆固体氧化物电池（rSOC）。在低互连微电网中，容量和功率的解耦规模是实现更高成本效益的基本特征。
