  1. BackgroundGrid energy storage, at its essence, allows electrical energy to be stored when production exceeds consumption and released when consumption exceeds production. Grid energy storage improves the robustness and resilience of conventional electrical grids and can supplement intermittent energy sources such as solar, wind, or tidal. In partic...

  2. BackgroundA common feature in photovoltaic (PV) systems is that their power output is unpredictable and unstable in nature (intermittent). Various storage technologies can smooth the stochastic power output levels but are neither cost-effective nor efficient. In addition, many PV systems are typically connected to the power grid, letting users feed...

  7. Spin torque oscillators (STOs) offer an innovative alternative to microwave power generation and energy efficient computing. However, both applications require phase locking of an array of STOs, which has so far been difficult to accomplish. Additionally, conventional STOs are difficult to couple electrically and magnetically, and they require a la...
