The application of SiC-based power conversion in utilities, including the FACTS devices, power electronic interfaces for distributed energy resources, and energy storage systems, can significantly improve the efficiency and reliability of the system, and reduce the system weight and volume.
Besides, energy storage systems are also introduced in distributed systems to stabilize the power output of renewable energy [22, 23]. The power electronic conversion system is the interface to connect the energy storage system with the power grid.
This can be achieved with a local energy storage system (ESS) and, in principle, two approaches can be followed for adding an ESS to a PV system. AC-coupled energy storage systems can be added to existing PV installations that already have an existing PV inverter without an integrated storage option.
In general, the choice of an ESS is based on the required power capability and time horizon (discharge duration). As a result, the type of service required in terms of energy density (very short, short, medium, and long-term storage capacity) and power density (small, medium, and large-scale) determine the energy storage needs .
Replacing centralized and dispatchable bulk power production with diverse small, medium-scale, and large-scale non-dispatchable and renewable-based resources is revolutionizing the power grid. The Energy Storage Systems (ESSs) have also been employed alongside RESs for enhancing capacity factor and smoothing generated power.
Grid level energy storage systems are used in frequency regulation, spinning reverse, peak shaving, load leveling, and so on. Besides, energy storage systems are also introduced in distributed systems to stabilize the power output of renewable energy [22, 23].
Traditionally, MOS-Inverters are named and rated according to the nominal battery voltage of the corresponding Pb-based battery system. With Li-Ion based battery systems or secondary power-management systems available, the rules for nominal operating voltages change. This change can be used to effectively boost the power that can be supported ...
