DATASHEET
Electrical power generation, transmission and distribution system operated for decades with limited intelligence. But present and future demands are necessitating a transition to a smart grid, particularly the need to incorporate distributed energy resources (DERs) onto the electrical grid. DERs are defined as small scale decentralized power storage and generation sites (10 Mega-Watts or less range). In most cases, these DERs are owned and operated not by the utility company, but rather by consumers. Power from DERs is used to meet the local end-user DER owner needs, however, excess power is then sold back to the utility via integration onto the power distribution grid.

Types of DERs include renewables such as solar photovoltaic, small wind power, and geothermal sites. Non-renewable DER sources include gas turbines, diesel engines, micro turbines, flywheel energy storage systems, fuel cells, batteries and super capacitors.

Governments worldwide are strongly encouraging and often mandating the incorporation of DERs into utility generation portfolios as DERs can be part of an overall green power generation solution. However, integration of DERs into the local distribution system and ultimately into the entire utility generation, transmission and distribution system is problematic for utility companies for a number of reasons, not just in terms of balancing generation with demand.

Over the years, utilities have devised a number of methods to find and repair problems on their distribution systems, all predicated on the flow of power through transmission and distribution systems from upstream generation to downstream customers. Frequent maintenance has kept problems to a minimum, but safely performing these activities often depends on the predictable power flow of a radial distribution system. DERs change the nature of power flows through the local distribution system, adding complexity and possible dangers.

Local distribution systems are designed so that sectionalizing devices such as circuit breakers, line reclosers, and manual switches/disconnects can route power through the system and around areas where work needs to be performed. Once an upstream device is locked out and tagged out, utility crews can be confident that the line is dead and safe for work. However, with DERs on the grid, power can be fed back into the local distribution system from a variety of sources located throughout the service area. Locking and tagging out a substation circuit breaker cuts upstream power, but a DER can back feed power into the system, causing unpredicatable and dangerous work conditions. This is just one example of the difficulties and challenges utility companies face when dealing with Distributed Energy Resources on the grid.
