Resumo:

Over the last several decades electric utilities around the world have deployed direct load control and demand side
management (DSM) programs of various types to reduce their peak loads during stressed conditions when the available
generation reaches its limit. This situation arises during special events, due to lack of available generation, or when
the system peak is very high due to weather conditions. Now this situation is exacerbated with the introduction of
intermittent sources of generation like solar and wind.

Under the widely practiced demand side management (DSM) programs, the electric utility turns off or cycles the residential
customers’ high voltage (240V) load (eg, electric water heater, air conditioner) during times of generation shortage.
Now with the gradual introduction of the smart grid and its associated hardware, software and control protocols, many more
options are becoming available for developing creative “demand response” programs where the customer has the ability to
choose how much load to control and when. This allows the electric utility to access a large number of customers on a
dynamic basis without having to depend on a preselected set. Moreover, this approach can be customized even for a small
segment of the network like a feeder that may have difficulty meeting its connected load due to some temporary resource
constraints.
This presentation focuses on the opportunities and challenges provided by the introduction of the smart grid to use demand
response as a tool to make renewable energy sources more valuable to the electric power grid.
