Furthermore, battery energy storage systems (BESS) are an important direct source of flexibility, as they can store and supply power to the grid almost instantly. In addition to facilitating near-real-time system balancing, BESS can also contribute to a range of services that support the grid. How can BESS help mitigate grid challenges?
3.1. Battery Energy Storage System The BESS consists of an active front end (AFE), with a 30 kV A nominal power, connected to the grid and to a DC low voltage bus-bar at 600 V through a DC link supplied by a 20 kW DC/DC buck booster and a Li-Polymer battery with 70 A h and 16 kW h total capacity.
Battery energy storage systems provide flexibility to maintain cost-efficient operation of the power system. Through revenue stacking, these storage systems offer a range of services that enhance the reliability and stability of the electricity grid and contribute to the system’s resource adequacy.
Although reactive power does not add to active power, it does play a significant role in the voltage level of the AC grid. Reactive power services are used to limit voltage levels within a given range. As reactive power is difficult to transmit, voltage has to be managed locally.
In addition, the main energy storage functionalities such as energy time-shift, quick energy injection and quick energy extraction are expected to make a large contribution to security of power supplies, power quality and minimization of direct costs and environmental costs ( Zakeri and Syri 2015 ).
If the absorbed reactive power is greater than a settled threshold in the measurement point, the BESS provides the reactive power given by the difference between the reactive power provided by the grid and the threshold. The result is limited to maximum reactive power of inverter׳s BESS.
