Distributed Solar PV for Electricity System Resiliency: Policy and Regulatory Considerations
-
To enable distributed PV that can supply electricity during grid outages, this paper presents approaches specifically to support resiliency through design of PV systems utilizing storage technologies, community energy storage, solar-diesel hybrid systems, and micro-grids. The paper also considers policies and regulations to support distributed PV that contributes to resiliency.

Standard for Integrating Distributed Resources with Electric Power System – IEEE 1547
-
Standard IEEE 1547 is an example of an interconnection standard (commonly used in North American power systems) providing technical rules for interconnecting distributed generation resources with the electric grid. The standard’s guide introduces the background and rationale for the technical requirements, facilitates use of the standard by characterizing distributed resource technologies and related interconnection issues, and provides approaches and information to support interconnection and implementation. The standard was updated in 2014 with an amendment providing existing information on voltage, voltage regulation, and frequency.
