Battery Energy Storage System for Large Scale Penetration of Renewable Energy Sources
Published by Ruchika, D.K. Jain, DCRUST, Murthal, Haryana Abstract. Battery energy storage system (BESS) plays a dominant role in large scale penetration of renewable energy sources into the grid. They help in a better match between the demand- supply during standalone mode and the grid connected mode. In this paper, the authors proposed a newContinue reading “Battery Energy Storage System for Large Scale Penetration of Renewable Energy Sources”
Practical 400 Hz use Cases for Aviation Teams
Published by Dranetz Technologies, Inc. Below are three situations aviation teams often face, and how the HDPQ Xplorer 400 helps resolve them. Jetway keeps resetting when an aircraft connects What’s happening: During bridge movement or aircraft power-up, the 400 Hz supply dips. Sometimes it is a brief sag, other times a fast transient that trips protection.Continue reading “Practical 400 Hz use Cases for Aviation Teams”
Energy Management for Healthcare Facilities
Published by Dranetz Technologies, Inc., Case Study Energy and demand costs have a direct impact on a company’s bottom line. In fact, the cost of energy is one of the most commonly mismanaged expenses, regardless of a company’s size or the industry represented. In healthcare facilities energy management can be more difficult than any other industry, becauseContinue reading “Energy Management for Healthcare Facilities”
