DER systems typically use [[renewable energy]] sources, including [[small hydro]], [[biomass]], [[biogas]], [[solar power]], [[wind power]], and [[geothermal power]], and increasingly play an important role for the [[electric power distribution]] system. A grid-connected device for [[Grid energy storage|electricity storage]] can also be classified as a DER system and is often called a '''distributed energy storage system''' ('''DESS''').<ref>{{cite journal |last1=Nadeem |first1=Talha Bin |last2=Siddiqui |first2=Mubashir |last3=Khalid |first3=Muhammad |last4=Asif |first4=Muhammad |title=Distributed energy systems: A review of classification, technologies, applications, and policies |journal=Energy Strategy Reviews |date=2023 |volume=48 |pages=101096 |doi=10.1016/j.esr.2023.101096 |doi-access=free|bibcode=2023EneSR..4801096N }}</ref> By means of an interface, DER systems can be managed and coordinated within a [[smart grid]].

One of the major issues with the integration of the DER such as solar power, wind power, etc. is the uncertain nature of such electricity resources. This uncertainty can cause a few problems in the distribution system: (i) it makes the supply-demand relationships extremely complex, and requires complicated optimization tools to balance the network, and (ii) it puts higher pressure on the transmission network,<ref>{{Cite journal|last1=Mohammadi Fathabad|first1=Abolhassan|last2=Cheng|first2=Jianqiang|last3=Pan|first3=Kai|last4=Qiu|first4=Feng|date=2020|title=Data-driven Planning for Renewable Distributed Generation in Distribution Systems|url=https://ieeexplore.ieee.org/document/9112707|journal=IEEE Transactions on Power Systems|volume=35|issue=6|pages=4357–4368|doi=10.1109/TPWRS.2020.3001235|s2cid=225734643|issn=1558-0679|hdl=10397/89857|hdl-access=free|url-access=subscription}}</ref> and (iii) it may cause reverse power flow from the distribution system to transmission system.<ref>{{Cite journal|last1=De Carne|first1=Giovanni|last2=Buticchi|first2=Giampaolo|last3=Zou|first3=Zhixiang|last4=Liserre|first4=Marco|date=July 2018|title=Reverse Power Flow Control in a ST-Fed Distribution Grid|journal=IEEE Transactions on Smart Grid|volume=9|issue=4|pages=3811–3819|doi=10.1109/TSG.2017.2651147|s2cid=49354817|issn=1949-3061|url=https://nbn-resolving.org/urn:nbn:de:gbv:8-publ-14890}}</ref>

Microgrids can disconnect from the centralized grid and operate autonomously, strengthen grid resilience, and help mitigate grid disturbances. They are typically low-voltage AC grids, often use [[diesel generator]]s, and are installed by the community they serve. Microgrids increasingly employ a mixture of different distributed energy resources, such as [[solar hybrid power systems]], which significantly reduce the amount of carbon emitted.
