The energy storage systems described in this publication are a natural addition to PV solar and wind power instal-lations. They facilitate the integration of renewable energy with the grid by virtue of capacity firming and ramp rate control functions. The end result is more eficient utilization and availability.
Table 1. Simulation parameters. Among them, the rated voltage of the power grid is 10 kV and the frequency is 50 Hz. The HVAC part of the energy storage PCS system contains 15 modules in each phase, with a three-phase Y-connection.
A modular battery-based energy storage system is composed by several battery packs distributed among different modules or parts of a power conversion system (PCS). The design of such PCS can be diverse attending to different criteria such as reliability, efficiency, fault tolerance, compactness and flexibility.
Large-scale energy storage is favorable currently. The capacity expansion needs to be realized by the parallel connection of multiple low-voltage small-capacity PCSs and connected to a medium- or high-voltage power grid through the transformer. The connection would lead to the problems of low efficiency, high cost and unnecessary land occupation.
With the enormous amount of energy being consumed in today's world and government policies to minimize carbon emissions, the shift to renewable energy makes reliably delivering energy where and when it is needed more challenging than ever. As a result, demand for energy storage systems is also on the rise.
The PCS is the intermediary device between the storage element, typically large banks of (DC) batteries, and the (AC) power grid. AC/DC and DC/AC conversion takes place in the power conversion system (PCS). The energy flows into the batteries to charge them or is converted to AC from the battery storage and fed into the grid.
