Dynamic Demand Management in an Airconditioner System by Frequency Control in Smart Grid Environment (original) (raw)

2016, International Journal of Smart Electrical Engineering

As there is a rapid growth both in the number of power consumers and also the limitations energy resources, it is clearly accepted that the old version of power grid must change into smart grid from head to toe. One of the most important advantages of smart grid which makes it much more exclusive rather than other typical systems is the two-way connectivity between the utility and the costumers. Taking energy efficiency programs for domestic consumers which are considered with the most important role in raising the rate of energy consumption of all, is accepted as an applicable techniques of demandside management. In this thesis an identical frequency method control of the electrical motor of an air-conditioner (AC) system based on Fuzzy-PID controller is proposed in order to maximizing energy efficiency. Referring to the statistics which are published about the rate of energy consumption of AC systems would have the highest role in demand response and the two-way cooperation betwee...

IJERT-A Novel Air Conditioner for Smart Grid Applications

International Journal of Engineering Research and Technology (IJERT), 2014

https://www.ijert.org/a-novel-air-conditioner-for-smart-grid-applications https://www.ijert.org/research/a-novel-air-conditioner-for-smart-grid-applications-IJERTV3IS060684.pdf This paper represents concept of fuzzy logic controller to adjust the temperature setting of the air conditioner by taking input voltage as the reference during peak demand hours. The control is directed to reduce the peak demand without sacrificing the customer's comfort level. The proposed concept is directed to increase the grid efficiency and to reduce the supply demand gap. The proposed fuzzy based controller is directed to increase the temperature settings of the AC by taking voltage drop as the reference value, thereby resulting into the reduced motor compressor operating time and reduced demand from the grid. When no. of ACs are assumed to be controlled by such controller, the peak demand on the grid can be reduced. This will help in reducing the greenhouse gases emission resulting due to polluting and expensive plants like coal, diesel and gas based power plants.

Energy Efficiency of a Variable Speed of the Centralized Air Conditioning System Using Pid Controller

Jurnal Teknologi, 2016

PID control system for air-conditioning system in residence is presented in this manuscript. The control strategy is focused on low energy consumption and thermal comfort for indoor user. The algorithm is developed to control the compressor speed at an appropriate speed according to the temperature inside the controlled area using PID controller. Software is developed to measure and interface the system with controlling the system according to the algorithm. The temperature settings are 20, 22 and 24oC with internal heat load of 0 and 1000 Watt. The results obtained proved that the technique can lower the energy consumption and increased temperature control for better thermal comfort compared to on/off controller

PID Controller for Optimum Energy Efficiency in Air-Conditioner

International Journal of Electrical, Energy and Power System Engineering

Air conditioning is a process of excluding moisture and heat in interior space for better thermal comfort. It is also one of the largest energy consumers in a household. The air-conditioner uses a lot of energy to maintain desired room temperature. The world is getting old and technologies are getting more advanced every day, energy-efficient appliances are needed to preserve the world. This paper presents a design and testing of the PID control for temperature and humidity control using Arduino to get the optimum energy efficiency. The system was developing by implementing the DHT22 sensor. The objectives of this work are; to design experimental model of air conditioning system, and to optimize the system using PID control. The Arduino is used in this work to showcase the temperature and humidity reading. The experimental model has been successfully built for use with PC fan with 12V and 0.26A current rate. The real-life performance is quite satisfactory.

Investigation and Field Measurements for Demand Side Management Control Technique of Smart Air Conditioners located at Residential, Commercial, and Industrial Sites

Energies, 2022

This paper investigates the response and characteristics of the narrowband power line communication (NB-PLC) technique for the effective control of electric appliances such as smart air conditioners (SACs) for demand side management (DSM) services. The expression for temperature sensitivity by examining the influence of atmospheric temperature variations on power consumption profile of all possible types of loads, i.e., residential, commercial, and industrial loads is derived and analyzed. Comprehensive field measurements on these power consumers are carried out in Lahore, Pakistan. The responses of low voltage channels, medium voltage channels, and transformer bridge for a 3–500 kHz NB-PLC frequency range are presented for DSM services. The master control room transmits control commands for the thermostat settings of SACs over power lines, crossing the transformer bridge to reach the SACs of power consumers by using communication protocol smart energy profile 1.0. The comparison of...
