Amongst a range of issues being reported in the research, the effect of these changes on so-called 'traditional protection systems' has not gone without attention. Looking to the future, the possibility of microgrid systems and deliberate islanding of sections of the network will require highly flexible distribution management systems and a e-designr of protection strategies. This paper explores the envisaged protection issues concerned with large penetrations of embedded generation in distribution networks extending into auto-reclosure and protection device coordination.

The low voltage network test feeder represents a or networked systems. The purpose of the 342-node Low moderate size urban system that is unbalanced and highly Voltage Networked Test System (LVNTS) is to provide a networked. This is the first distribution test feeder developed by benchmark for researchers who want to evaluate if new the IEEE that contains unbalanced networked components. The algorithms generalize to non-radial distribution systems. The 342-node Low Voltage Networked Test System includes many LVNTS has been designed to present challenges to elements that may be found in a networked system: multiple distribution system analysis software in the following areas: 13.2kV primary feeders, network protectors, a 120/208V grid network, and multiple 277/480V spot networks.

  • Photovoltaic Systems Interconnected Onto Network Distribution Systems
    3.0 Radial Distribution Systems Radial distribution systems (RDS) are the most common design used by electric utilities, and are the least expensive to plan, construct, and maintain. They generally consist of an electrical substation (typically at medium voltage in the 15 kV class), radial feeders for energy delivery (which may be a few miles to a few dozen miles in length), and eventually tie to transformer(s) that convert the 15 kV voltage to a utilization level (120/240, 120/208 or 277/480). There are typically several hundred to several thousand electric utility customers on a feeder, and anywhere from one to twenty customers who may be served by selective transformers. Depending on the type of service agreements, these customers may be metered at either the primary voltage level (e.g. 15 kV class) or the utilization level. Radial distribution systems are the simplest systems to plan, construct, and maintain, but are also the least reliable because of the radial nature of the design being served from a single source at a time. If any part of the system experiences a failure, some or all of the customers served by the radial feeder will be without power until a repair is completed. Straightforward design, lower cost, and decent reliability are the distinguishing characteristics of the RDS. An auto-loop distribution system is a special type of radial distribution system and is differentiated by having two feeders that tie to a customer load. The auto-loop system automatically senses the loss of one source of voltage and quickly and automatically switches the load to the second feeder.

  • Pepco Smart Grid Presentation
    Pepco’s Plans for Smart Grid Rob Stewart Blueprint Technology Strategist 0 Pepco’s Smart Grid Vision… “Through the ‘Smart Grid’, customers will become empowered to make choices regarding their use and cost of energy. It will open opportunities for innovation. It will provide the ability for a utility and its customers to take advantage of energy alternatives and efficiencies regarding both the production and consumption of energy. It includes a solid foundation of intelligent grid sensors, components and operational design to improve control, quality, reliability, and security. Adding, operating and maintaining grid assets will be based upon more up-to-date, fact-based data. This will enable the evolution from preventative and reactive to predictive and self healing for more efficient use of resources.” Vision, without an Action Plan, is just a Dream…… 1 Pepco believes there are 5 evolutionary steps to achieving the Smart Grid… Step 5 Optimization: Step 4 – Capability of real-time • Analytical optimization of infrastructure: distribution Step 3 network – Development of performance new data Integration: – Decisions based analysis – Corporate IT on near real-time Maturity Step 2 capabilities systems information, no • Communications integrated to allow – Increased ability longer only to display infrastructure: rapid processing historical data Step 1 of data information (in – Enterprise – Open architecture form of • Intelligent devices communication based design to dashboards, system for rapid infrastructure: facilitate sharing etc.) and accurate
