The 21st Century Power Partnership supports global power sector transformation. The Partnership has developed a curated, annotated resource library that provides reports, academic literature, case studies, and good practices to support distributed generation regulation in a variety of power system contexts. The library is organized around several topical areas: Ratemaking, Understanding Impacts, Interconnection, Alternative Business and Regulatory Models, Planning, and Case Studies.

To enable informed decision-making and planning related to increasing levels of distributed PV resources, the Distributed Generation Interconnection Collaborative facilitates knowledge sharing among its members about distributed PV interconnection practices, research, and replicable innovations. While the Collaborative itself primarily works with utilities and other stakeholders in the United States, its website hosts a collection of presentations, webinars, and reports that provide more broadly applicable information and case studies on interconnection practices.

High penetrations of PV on a distribution system can lead to reliability impacts related to overload, voltage, reverse power flow, protection, and circuit configuration. Drawing on the results and lessons-learned from a five-year study of the Southern California Edison (SCE) distribution system from 2010 – 2015, this handbook presents a detailed analysis of the potential impacts and mitigation techniques of PV integration. Written for distribution engineers, the handbook also provides a model-based study guide for assessing PV impacts, covering topics such as model development, data validation and measurement, study criteria, and the steps involved in power flow and fault analysis. While the impacts and mitigation techniques described in this handbook are derived from research that focused on the integration of utility-scale PV systems (1-5 MW), much of the information is also relevant for the integration of a large number of small, distributed PV systems.

Estimating the benefits and costs of achieving significant deployment of distributed PV helps power system stakeholders evaluate regulatory measures and compensation programs for distributed PV. To inform these decisions, this report describes current and potential future methods, data, and tools that could be used with different levels of sophistication and effort to estimate the benefits and costs of distributed PV from the utility or electricity-generation system perspective. Although the report is explicitly written in the context of informing estimation of distributed PV costs and benefits to the United States electricity system, the discussions of the various methods, level of effort, and data and modeling requirements provide insights relevant to power systems outside of the U.S. The report provides methodologies for estimating distributed PV benefits and costs for the following categories: energy, environmental, transmission and distribution losses, generation capacity, transmission and distribution capacity, ancillary services, and other factors.

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.

Traditional interconnection processes evaluate the impacts of a given distributed generator to safety, reliability, and power quality after an interconnection request is received. This concept note introduces “Integrated Distribution Planning,” an alternative, emerging methodology designed to enable distributed PV. In the Integrated Distributed Planning concept, utilities or distribution system operators proactively study the hosting capacity of distribution circuits, the ability of these distribution circuits to accommodate growth in distributed generation, and any necessary infrastructure upgrades, all in advance of receiving interconnection requests from generators.

Solar Potential Analysis Report for Minnesota
Clean Power Research has released a new report as part of the Minnesota Solar Pathways initiative. The report details the results from their grid integration study on the generation cost to achieve 10% of Minnesota’s electricity from solar by 2025 and 70% of Minnesota’s electricity from solar and wind by 2050.
