Scheduling of air conditioner based on real time price and real-time temperature

The smart grid initiative and the market operations drive into the new concept of control able loads. This particular Paper presents a smart scheduling device of an air conditioner which demonstrates the general architecture along with practical implementation of the hardware that could be use to schedule the air condition based on real time price and temperature in order to reduce the cost of electricity bill, devoid of compromising the user comfort. The proposed architecture of overall system comprise of three parts, Data collection Part, Scheduling Part and Control part. The system collects outdoor temperature as well as dynamic price in real time. Scheduling part serves as brain of proposed system and is responsible for taking decisions based on input parameters. It determines an optimal choice of energy consumption scheduling which keeps into consideration the user comforts and formulated as nonlinear programming. Results were then applied to the air conditioner in the form of on/off and setting thermostat with help of the control unit which consisted on the infrared transmitter and receiver. At last a test bed was designed and experimental results shown that the electricity expenditure is reduced, along with that the overall suitable temperature is also maintained.
