What are distributed energy resources der?
Distributed energy resources are small, modular, energy generation and storage technologies that provide electric capacity or energy where you need it. Typically producing less than 10 megawatts (MW) of power, DER systems can usually be sized to meet your particular needs and installed on site.
What are examples of distributed energy resources?
Examples of distributed energy resources that can be installed include:
- roof top solar photovoltaic units.
- wind generating units.
- battery storage.
- batteries in electric vehicles used to export power back to the grid.
- combined heat and power units, or tri-generation units that also utilise waste heat to provide cooling.
What is Der in utilities?
A Distributed Energy Resource (DER) is any resource on the distribution system that produces electricity and is not otherwise included in the formal NERC definition of the Bulk Electric System (BES). This definition only applies to resources on the utility side of the customer retail meter.
Who regulates distributed resources?
The CPUC
The CPUC regulates services and utilities, protects consumers, safeguards the environment, and assures Californians’ access to safe and reliable utility infrastructure and services. For more information on the CPUC, please visit www.cpuc.ca.gov.
How does distributed energy resource work?
DERs provide energy value when they displace the need to produce energy from another resource. DERs provide operating reserve value when they can be used to increase supply or reduce demand on the grid in place of central generators that would otherwise be used in case of contingencies (e.g., forced outages).
What are the characteristics of distributed energy resources?
C. Characteristics of DER
- Premium power—reduced frequency variations, voltage transients, surges, dips, or other disruptions.
- Back-up power—used in the event of an outage, as a back-up to the electric grid.
- Peak shaving—the use of DER during times when electric use and demand charges are high.
Is solar a Der?
A particular industry interest seems to be centered on DERs — such as solar, storage, energy efficiency, and demand management — that can be aggregated to provide services to the electric grid.
What is a DER system?
Distributed energy resources (DER) are electric generation units (typically in the range of 3 kW to 50 MW) located within the electric distribution system at or near the end user. They are parallel to the electric utility or stand-alone units.
What is distributed power generation system?
About Distributed Generation Distributed generation refers to a variety of technologies that generate electricity at or near where it will be used, such as solar panels and combined heat and power. In the residential sector, common distributed generation systems include: Solar photovoltaic panels. Small wind turbines.
How do DERs work?
DERs provide distribution-level capacity value when they defer or avoid investment in distribution assets. DERs provide power quality value to distribution systems by modulating their production and/or consumption of power; e.g. providing reactive power to improve voltage profiles on distribution feeders.
What is DG solar?
Electricity produced at or near the point where it is used is called Distributed Generation (DG). Distributed solar energy can be located on rooftops or ground-mounted, and is typically connected to the local utility distribution grid.
