IEEE Green Energy and Smart Systems Conference
Long Beach, CA, October 29-30, 2018


Topic: Smart Inverters/converters overview

Abstract: The implementation of solar Photovoltaic Inverters as a means of generation has been growing exponentially in California. Solar PV generation was less than 100 Mega-watts before 2009 to several thousands of megawatts by 2018. This rapid increment of solar PV inverter generation had the need for smart features on solar PV inverters to minimize their impacts on the grid furthermore to provide support during grid emergencies. This talk will cover the solar PV inverter standards upgrades needed for high penetration levels as well how smart inverter features can support the electric grid. Additionally, will cover both laboratory and field experiences with solar PV generation.


Richard J. Bravo is a senior engineer with Southern California Edison’s Advanced Technology group. Bravo has worked on various projects in distribution system, including the upgrade of motor control centers (MCC), control systems upgrades for pipelines, Fault Induced Delayed Voltage Recovery (FIDVR), SCE satellite communications, dynamic performance of residential and commercial loads, SCE’s solar PV inverter generation performance. Bravo has supported the solar PV standards such as: California Rule 21, IEEE-1547 and UL-1741. He also have worked with the Western Electricity Coordinating Council (WECC) in the development of computer models for system planning studies. Bravo earned his master’s and Bachelor of Science degrees in electrical engineering from California State University at Long Beach. He earned a Power Systems Sequential Program certificate from the University of California at Los Angeles and holds a professional engineer license in electrical engineering from the State of California.


Topic: Electricity Storage in Utility Applications

Abstract: The adaption of energy storage as a means of generation has been growing exponentially in California. The increase penetration of Solar PV and wind generation has major impacts on grid management.  . Energy storage is key to maximize the benefits of renewables and ensure that their integration leads to a reliable and affordable electricity supply. In October 2013, the California Public Utilities Commission (CPUC) adopted a 1,325 megawatts (MW) procurement mandate for electricity storage by 2020, with targets increasing every two years between 2016 and 2020. An additional four laws were adopted in 2016 to increase and help reach this initial goal.

This talk will cover the current energy storage technologies, their characteristic and their impact on the bulk power system operation and control.
