Power Distribution Systems with Energy Storage Systems (ESS)

Installing Energy Storage Systems (ESS) and Photovoltaic (PV) equipment into power distribution systems can be complicated and expensive. However, Power Control Systems (PCS) introduced into the 2020 National Electrical Code (NEC Article 705) now allow more ESS + PV connected power to new or existing services while minimizing bus sizes, thus making retrofits easier and optimizing new installations. Also, UL1741 is a new safety and performance standard which is used to certify PCSs, as well as the smart inverters, converters, and the interconnection of Distributed Energy Resources (DERs) in the system.
This presentation offers a brief review of NEC 705, and the PCS which meets UL listing requirements. Though applicable to power systems in general, the presentation offers a residential home as an application example of the value of a PCS. The presentation discusses how it affects busbar loading and offers a way to integrate an ESS into existing or new systems.
In summary, the PCS, and associated standards make it easier for engineers and installers to maximize the use of multiple energy inputs for efficiency and cost, while ensuring safety and reliability.
