A PVC-based membrane containing cerium phosphate was developed. Unlike the cerium phosphate itself that acts as a cation exchanger, the membrane exhibited anion-exchange properties. Therefore, the utility of this compound as a sensory element for detection of molybdate ions was pursued. The response of molybdate selective electrode based on this membrane was perfectly linear in the concentr...

This article reports on lessons learned from installing a photovoltaic system at Elmira High School through cooperation between Emerald People’s Utility District (a local utility), Bonneville Power Administration, and Western SUN (a utility oriented photovoltaic system wholesaler). Key factors needed for this project were interest from the school, advantages for the local utility in installing ...

Author: Andre Szykier CEO/CTO GridPlex Networks LLC Copyright © 2010 P ag e1 Demand Response and Grid Management are power utility initiatives driven by Federal and State stimulus programs to make the electric grid more reliable, secure and intelligent. The first step in making a grid “smart” is by replacing existing end user power utility meters with smart meters that support bi-directional co...

This paper describes a power electronic system that, among other possibilities, can be used to charge electric vehicle batteries. A large-signal linear, multirate digital controller for the charging current permits the charger to track and deliver a desired current trajectory for a wide range of loads. This controller simultaneously ensures that the charger draws power from the electric utility...

This paper presents a hierarchical control strategy for heat and electric power control of a building integrating hybrid renewable power sources including photovoltaic, fuel cell and battery energy storage with Plug-in Electric Vehicles (PEV) in smart distribution systems. Because of the controllability of fuel cell power, this power sources plays the main role for providing heat and electric p...

To understand the real world conditions of use of plug-in hybrid electric vehicles, the electrical energy consumption and gasoline energy consumption must be weighted according to how often a consumer will drive fueled by each energy source. To perform this weighting The Society of Automotive Engineers Hybrid Committee has codified the concept of the utility factor in SAE J2841 Utility Factor D...
