    The variable operations of weather-related Distributed Energy Resources in distribution systems cause voltage fluctuations at different buses of the distribution circuits. These fluctuations may significantly impact the power quality as well as the reliability of other volt/var controlling devices. Compensating changes of the DER reactive power may be used to mitigate these voltage fluctuations. This paper discusses two methods of such compensation, compares them in terms of a number of operational criteria, and presents an illustrative numerical example.

    Thermal standards for homes were established to improve thermal performance by strengthening the barrier between outside and the conditioned interior. A checklist of thermal standards is included in the energy code. For example, wall insulation in Oregon has to be rated at least R-21. A building inspector verifies compliance for each component of the thermal shell: foundation, underfloor, walls, roof, skylights, doors and windows.

    Today's power distribution control center manages the day-to-day operation of distribution network to ensure uninterrupted power supplies to the end customers. Today there is limited automation in distribution networks which results in lack the holistic visibility of real-time situation for an operator. With the advent of Smart Grid, there is an increase in development of next generation sensors, controllers and standard based system integration tools.

    AMI (Advanced Metering Infrastructure) programs are typically quite complex and burdensome for the utilities, fraught with risks and challenges during their journeys towards successful implementations. Managing and mitigating the multitude of challenges and risks during an AMI implementation life cycle can drain the utilities of their energy and shift their focus away from their core day to day business activities. In this situation, AMI Managed Services...

    Transmission and Distribution utilities which operate and maintain huge network of infrastructure assets will have business and technological challenges in the near future due to ever increasing needs of managing real-time information. Availability of low cost tablets and smart devices in the marketplace with improved processing power is triggering bigger investments from utilities in this area and hence would require better focus and attention in the coming days.

    I think that it is common sense that the definition and understanding of the problem is always the first step to creating a solution. The main obstacle to the implementation and development of an "Intelligent Network" is that it is designed, engineered and thought to be used by the "Consumer of the Future", but who must support and pay the "Bill" are the "Current Consumer".

    As European countries move closer to wide-scale adoption of Smart Metering technology, the need for a co-ordinated approach among product vendors, solution designers, communication technologists and individual utilities has never been clearer. If diverse technologies are to work together seamlessly, then standards for various aspects of the optimal system design are required.

    The communications system -- which may include SCADA equipment, transceivers, and backup batteries - affiliated with a utility's Transmission and Distribution lines will require protection from the elements, thermal management to maintain the proper operating temperature ranges, and security to prevent malicious access and tampering.

    While there is much interest in developing various forms of energy storage at the present day, the popular contemporary technologies involve high capital cost. Many researchers have actively been seeking alternative mobile and stationary technologies that involve lower capital costs. Part of this research has revolved around increasing the energy storage capacity of classical thermal energy storage technologies.
