   Fundamental Tarification of Electricity
By Alex VAN DEN BOSSCHE, Bart MEERSMAN, Lieven VANDEVELDE [View]
[Download]

Abstract: Over the past decade, Power Quality (PQ) issues became increasingly important. The most cited PQ problems are voltage dips, harmonic distortion and transient phenomena. The tarification method which is mostly used, tarifies the instantaneous active power. When absorbing harmonic power, e.g. when using an active filter, the customer has to pay for this. To overcome this, a tarification method is proposed. The FUndamental Tarification (FUT) method which is proposed tarifies a power which is based on the fundamental component of the grid voltage. An exaggerated effect can be implemented such that the customer is remunerated for increasing the Power Quality by absorbing harmonic power.

   Realizing Standby Operation of a Television with Zero Energy Consumption

Abstract: The energy consumption of consumer electronics while in off state is a never ending discussion and leads to always improving and more complex solutions. This paper shows our experiences with a concept completely removing such consumption while maintaining the most important remote control functionality.

   Variable Refrigerant Flow: Demonstration of Efficient Space Conditioning Technology Using Variable Speed Drives
By Ammi AMARNATH [View]

Abstract: Variable Refrigerant Flow, or VRF, systems are popular in Japan for buildings’ space conditioning needs, but have a very small market penetration in the United States. These systems are energy efficient and provide considerable comfort to occupants. Highly efficient motors, variable speed drive system and controls are the heart of the VRF technology. This paper provides research conducted by the Electric Power Research Institute (EPRI) of the U.S. by installing a VRF system within nine of the offices at its Knoxville, Tennessee building. The system was relatively easy to install and retrofitting was not an issue. The system provided individual cooling and heating to each office; it was very quiet and operated very well under partial load conditions. Survey conducted by EPRI found that occupants preferred the VRF system over the existing ducted space conditioning system. For a given amount of cooling at an equivalent external temperature, the VRF system exhibited 20-40\% reduction in energy consumption, while improving occupants’ comfort at the same time. The paper also provides brief update on the motor and drive technology used by the VRF system; this is the under pinning technology for energy efficiency.
