Distributed Energy Resources systems increasingly play a crucial part in the distribution of electric power and typically use renewable energy sources including small hydro, biomass, biogas, solar, wind, and geothermal energy. The term "Distributed Energy Storage System" is frequently used to refer to a grid-connected electricity storage device (DESS). Distributed Generation systems inside a smart grid can be managed and coordinated via an interface. Energy may be gathered from a variety of sources thanks to distributed generation and storage, which may also have a positive impact on the environment and supply security.
The erratic nature of these electricity resources is one of the main problems with the integration of DER like solar power, wind power, etc. In the distribution system, this uncertainty may result in the following issues: In addition to increasing pressure on the transmission network and making supply-demand interactions exceedingly complex, it also increases the likelihood of reverse power flow from the Distributed Generation to the transmission system.
