Abstract:
Demand response provides an opportunity for consumers to play a significant role in the
operation of the electric grid by reducing or shifting their electricity usage during peak
periods in response to time-based rates or other forms of financial incentives. Methods of
engaging customers in demand response efforts include offering time-based rates such as
time-of-use pricing, critical peak pricing, variable peak pricing, real time pricing, and
critical peak rebates. It also includes direct load control programs which provide the ability
for power companies to air conditioners and water heaters on and off during periods of peak
demand in exchange for a financial incentive and lower electric bills. Demand response is
often associated with the short-term changes targeted for the critical hours during a day/year
when the demand is high or when the reserve margin is low, whereas the long-term changes
in the electricity consumption achieved through investments in energy efficiency or
changes in customer behavior are often referred to as Demand Side Management which is
an effort realized by the demand side only to improve energy efficiency.
In this project we will implement the Priority based demand response system for the
residential loads. It will be a general system in which a prototype for single house is made.
The number of appliances will be taken from the user and priority to each appliance will
be given depending upon the user’s comfort level. This program will check each appliance
in the order from the lowest priority to the highest priority. The load needed to be shifted
will be calculated and depending upon that the load will be shifted from the peak to off
peak time. The user will be given the control of the appliances using mobile application.
