In anticipation of significant growth in distributed PV in India, this report reviews global and Indian policies and regulations for distributed generation; identifies technical challenges to significantly increasing grid-connected distributed PV; and makes recommendations for addressing power quality, safety, grid stability, and distribution system operation issues. The report provides an example of a country-specific review and synthesis of best practices to inform national and state-level technical and grid code specifications, advanced inverter functionalities, and meter technology considerations, certification, and testing processes.

Germany leads the world in deployment of distributed PV, with PV generation contributing approximately 40% of peak power demand during some hours of the year. This article outlines the impacts of high PV deployment in Germany on grid stability and power flows in the transmission and distribution system. It also highlights practical solutions that Germany has implemented to support frequency and voltage control and reduce congestion, and suggests new concepts for voltage-control strategies.

The Federal Energy Regulatory Commission of the U.S. (FERC) Order No. 764 is an example of a regulation that reduces barriers for variable RE by requiring transmission providers to offer sub-hourly transmission scheduling for their customers. The Order also requires new interconnection requests from customers with large variable RE to provide meteorological and forced outage data to transmission providers, in those cases where the provider conducts variable RE forecasting.

Mexico is a regional leader in setting goals for reducing greenhouse gas emissions (GHG) and distributed generation (DG) development is a key priority for the country's policymakers. Current DG policies have fostered growth but need to be modernized to serve current needs and accommodate higher penetration levels. In this report, NREL summarizes international DG policy experiences and best practices and identifies the potential opportunities for policy reform.

Countries around the world have established ambitious targets for increasing the contribution of renewable energy toward meeting their national energy demand. At low penetrations of wind and solar (e.g., below 5%–10% of annual electric demand), impacts to the power system are likely to be minimal. However, as the proportion of variable renewable energy (VRE) connected to the grid increases, power system planners will increasingly need to evaluate and manage the impact of increased variability and uncertainty on system operations. They will also need to ensure that the policy and regulatory environment offers sufficient certainty and revenue streams to encourage investment in new VRE generation. To address these needs, power system planners can take several steps to align targets and incentives with grid integration considerations.

Mexico's energy reform will have far-reaching effects on how people produce and consume electricity in the country. Market liberalization will open the door to an increasing number of options for Mexican residential, commercial, and industrial consumers to deploy distributed generation (DG). Distributed generation is an option for consumers who want to produce their own electricity and provide electricity services to others. This report seeks to provide guidance to Mexican officials on designing economic and regulatory policies for DG.
