Optimization is the process of making a system as good as possible. But even though the concept is simple, the practice is complex because it involves multiple variables and tradeoffs. In the case of the power grid, we must find just the right balance between reliability, availability, efficiency and cost. Fortunately, the smart grid offers solutions. First, smart devices gather information, providing a more accurate and detailed understanding. Second, smart software analyzes that data and suggests adjustments to wring maximum value from grid assets.

Voltage optimization for energy savings can be an attractive energy conservation investment. But as EPRI Research Director Mark McGranaghan points out, the unknown for evaluating the impact of voltage optimization is the response of different types of loads to the voltage reduction. He says a new industry-wide initiative that addresses the modeling need from two different approaches is required. He details both inside. |

Voltage dips (also known as “voltage sags”) are short-duration reductions in voltage magnitude. Their duration is typically between a few cycles of the power-system frequency and a few seconds. The interest in voltage dips is mainly due to their impact on end-user equipment. Industrial processes may malfunction or shut down due to a voltage dip resulting in significant financial losses. Voltage dips are due to short-duration increases in current magnitude, whereas voltage dips due to short circuits and earth faults are of most concern for customers. This report presents the results from an international working group sponsored by CIGRE, CIRED and UIE aimed at improving the understanding of the compatibility between installations and the electricity supply. |

Company execs told Jesse Berst they were able to save 1 1/2 cents per kilowatt hour when they applied their new demand response initiative to NYC’s Rockefeller Center. Now Schneider Electric is targeting 200 of Chicago’s biggest buildings and expects to pull 150 MW out of the current demand of 800 MW. But energy efficiency is just part of this intriguing story. Jesse explains how if you follow the money you’ll see that Schneider may be onto something big. |

We talked for many years about "managing" distribution networks and "visualizing" them or making them "more efficient." Now people in the know are beginning to talk seriously about "optimizing" the Smart Grid. Click inside where I’ll tell you about an intriguing young company that claims to have the “secret sauce” for grid optimization – and big plans to stir things up. |

This paper puts forth the argument that growth of large central station wind and solar farms, a national priority, will be stymied until existing transmission capacity is increased using new technology (FACTS, optimized transmission dispatch, high capacity conductors, advanced storage, etc.) along with the addition of new high capacity high voltage direct current (HVDC)—800 kV—and high voltage alternating current (HVAC)—765 kV lines. Bottom line: while it is true that today’s transmission is more advanced than distribution, the transition to a smart grid requires much more transmission capability and now is the time to make the required investment.

Electric utilities have pursued devices that can limit fault current levels in transmission and distribution systems while remaining “electrically invisible” under nominal conditions. These fault current limiters (FCLs) have the potential to significantly alleviate power system stress in locations where fault current magnitudes are expected to increase beyond the duty of existing circuit breakers. Today’s superconducting materials can meet the performance requirements of power system components. As a result, a significant portion of proposed FCL designs use superconducting materials to achieve the limiting action. This report investigates the current status of these superconducting fault current limiter (SFCL) technologies and describes ongoing efforts to use them in electric power grids. |

This report supports development of a superconducting, long-distance, high-power capacity DC transmission system configured with multiple taps such that power can be easily be injected from generating plants and removed to serve loads all along the cable. The technology that will enable the construction of such a system is based on so-called "voltage source converters." The superconducting cable used for transfer of the power will have zero dc conduction losses. These technologies, when commercially available, could make a high-voltage DC system perform in ways similar to present-day ac systems by facilitating tapping of the dc circuit. This would make DC more competitive with ac for high-power corridor applications. |
