Distributed generation in power system ppt

What is distributed generation (DG)?

This document discusses distributed generation (DG), also known as on-site power generation located near the load. DG provides benefits to end-users, distribution utilities, and power producers. It examines various DG technologies like reciprocating engines, combustion turbines, fuel cells, and renewables.

What is the main function of a distribution substation?

Voltage transformation: The primary function of a distribution substation is to reduce the voltage down to the distribution voltage level. In Figure, only one transformer is shown. Other substation designs will call for two or more three-phase transformers. There are many “standard” distribution voltage levels.

How can distributed energy resource management systems help inverters?

Distributed energy resource management systems (DERMS) and/or ADMS may be able to aid in this effort. With proposed DERMS capabilities (Grid Management Working Group 2017), DERMS could modify inverter power factor (PF) and settings as well as dispatch or broadcast randomized response times for inverters, which would support these functions.

How can distribution utilities reduce energy consumption?

For example, through the integrated use of advanced inverters and other legacy voltage-control devices, distribution utilities can regulate entire-feeder voltage and reduce energy consumption.

What is the aggregate generation capacity of a small generating facility?

If the proposed Small Generating Facility is to be interconnected on single-phase shared secondary, the aggregate generation capacity on the shared secondary, including the proposed Small Generating Facility, shall not exceed 20 kW.

Do utilities have minimal distribution system data?

Additionally, many utilities have minimal distribution system data. In general, new issues arising around concentrations of smaller DER systems and associated changes in their system impacts, including DPV on new housing developments or third-party owned DER aggregations.
