Princeton Power & ZBB Announce Micro Grid Installations of Distributed Energy Storage Systems
Princeton Power Systems (PPS) announced that it has turned on its Energy Storage System (ESS) at BMW Group’s Technology Office in Mountain View, CA. The ESS is described as the first of its kind to use PPS’ new Demand Response Inverter in an integrated system.
The ESS, consisting of a 100kW Demand Response Inverter (DRI-100) and 30kWh lithium ion batteries, will be used to store renewable energy from the on-site solar array, reduce peak electricity demand and demonstrate dc fast charging technology for electric vehicles. The Princeton Power ESS is just one piece of BMW Group Technology Office’s USA e-mobility lab, a smart-home and electric vehicle ecosystem demonstration.
The DRI’s direct DC power routing capability demonstrates one of its critical advantages over other available inverters on the market. "These advanced capabilities make BMW’s charging system much more flexible than a typical charging station, and suitable to the deployment of both electric vehicle charging and smart grid applications," said Darren Hammell, Executive Vice President at Princeton Power Systems.
ZBB Energy Corp. announced that ZBB and its construction partner, City Cottage Group, have successfully installed and commissioned a 500kWh energy storage system and advanced power electronics for use in a micro grid application at the Illinois Institute of Technology (IIT) Campus in Chicago, IL utilizing ZBB EnerStore™ advanced energy storage technology and ZBB EnerSection™ inverter modules.
Funded by IIT and the US Department of Energy (DOE), the "Perfect Power" micro grid system at IIT is described as the first energy distribution system of its kind in the United States. IIT’s system will reduce the time and money lost to power outages and will meet IIT’s growing, specialized energy needs. In addition, it can be operated as a stand-alone power system in the case of grid contingencies.
Opinion: Distributed Generation Drives Industry Transformation
The ZBB EnerSystem has been integrated into the ITT micro grid prototype to provide critical system backup, load-shifting, peak load reduction, and improved integration of distributed renewables. ZBB’s EnerStore battery modules will also be used to offset the addition of new electric vehicle charging stations by storing off-peak power for use during day-time peak charging periods. ZBB EnerStore flow batteries were selected for the energy storage component because they are constructed from environmentally friendly materials that provide for long service life and advanced performance when compared with traditional chemical batteries.
"This commissioning is a significant milestone for ZBB Energy and provides a blueprint that can be used to replicate our systems for use in other micro grids worldwide," said Eric Apfelbach, President & CEO of ZBB Energy. "IIT, City Cottage Group and the Galvin Perfect Power Institute are valuable partners in demonstrating why new technologies like ZBB’s energy storage and advanced power electronics are critical components for the effective build-out of micro grids across global markets."

Energy Efficiency with Class D Amplifier Modules
Class-D switching amplifiers are helping audio designers create personal multimedia devices and home audio/visual systems that demonstrate how compact and stylish equipment can also deliver high sound quality and high audio output power. The key to this breakthrough, providing freedom from the large and bulky boxes housing traditional audio products, lies in the class-D amplifier’s high energy efficiency, which is typically around 90%. This allows designers to reduce or eliminate heatsinks as well as using smaller-sized PCBs and smaller components such as transformers, connectors and power supplies.

The Role of Hall Effect Sensors in Power Distribution Infrastructure
Power distribution units (PDUs) form an essential part of modern computing and data communications hardware. They provide multiple outputs for transferring electrical power with maximum efficiency, controlling the power capacity and safeguarding against the possible causes of supply interruption. With an ever increasing need from tech savvy consumers for higher data throughput and greater quantities of data storage capacity, as well as tough international legislation now governing CO&sub2; emissions, the demands being placed on these units are proving challenging for engineering teams to satisfy.
