Advanced Inverters for Distributed PV: Latent Opportunities for Localized Reactive Power Compensation
Updated May 13, 2013. This study by UC Berkeley and the Clean Coalition outlines the opportunity for localized management of reactive power by using advanced inverters coupled with distributed PV systems to provide reactive power adjacent to the point of use, as is being done in Germany. Furthermore, the study evaluates the feasibility of a Germany-like system in the United States.
Published October 18, 2013. This article by the Clean Coalition argues that advanced inverters should be treated as a cost-effective tool to optimize power quality, system reliability, and ratepayer economics through distributed voltage regulation. Given the system wide benefits, utilities should handle the costs of advanced inverters just as they handle the costs of traditional voltage control solutions, such as capacitor banks and synchronous condensers.
Updated February 11, 2014. Mr. Lewis’ presentation addresses the California Independent System Operator’s infamous ‘Duck Chart,’ which predicts significant grid reliability challenges later this decade. Through the use of preferred resources, California can ensure power system reliability while staying aligned with the state’s established climate and energy goals.
Updated November 5, 2013. This presentation highlights how distributed generation integrated with intelligent grid solutions (DG+IG) balance power, voltage, frequency, which creates a far more reliable and efficient electrical system.
Published March, 2014. This report details how energy storage can address policymaker concerns about solar. Distributed energy storage promises to change the electricity system during the next decade, as fundamentally as distributed renewable energy has in the last decade.
Hunters Point Project Overview
Coming soon. In collaboration with Pacific Gas & Electric and in support of the city of San Francisco’s goal to achieve a 100% renewable electricity supply, the Clean Coalition is spearheading a groundbreaking project to bring clean local energy online in San Francisco. The Hunters Point Project, named after the substation that serves both the Bayview and Hunters Point areas in San Francisco, will prove that clean local energy can fulfill at least 25% of total electric energy consumption in the area.
Updated April 9, 2014. This document details the substantial economic, energy, and environmental benefits brought to the local area by the Hunters Point Project.
Updated December 16, 2013. The Clean Coalition has modeled how intelligent grid solutions — such as demand response, advanced inverters, and energy storage — can support the integration of high penetrations of renewables onto the grid.
