The recent worldwide measures for energy savings is a larger awareness of the household energy consumption, which gives the relevant contribution of the domestic load to the national energy balance. This is mostly triggered by government decisions to fulfill energy-saving targets. A smart power monitoring and control system has been designed and developed toward the implementation of an intelligent building. Where the developed system effectively monitors and controls the electrical appliances. Thus the system used to determine the areas of daily peak hours of electricity usage levels. This can lower energy consumption and enhance better utilization of already limited resources during peak hours. The system principally monitors electrical parameters of household appliances such as voltage and current and subsequently calculates the power consumed. The novelty of this system is the implementation of the controlling mechanism of appliances based on traffic condition during peak demands. The developed system is low-cost and flexible in operation and thus can save electricity expense of the consumers. The overall system controls the gas leakage, fire detection, and PIR motion detection. ARM processor application is used to control the device through the web page by using GSM communication.
Proposed Home Automation System
The current values of home appliances are sensed by using hall effect current sensor ACS712 and they are monitored in Proteus has been proposed in this paper. In the existing method, ASM010 current sensors use. It produces the non-accurate output voltage when the surges present in the load. So, power cannot be calculated correctly. But the Hall-Effect current sensor produces the output voltage without any loss. So the accurate power can be calculated. This system controls the gas detection, fire detection, and motion detection. ARM processor used to control the device through a web page by using GSM communication.
In this, the current and voltage sensors which sense the current and voltage values of the home appliances. Pyroelectric effect sensor senses the authorized person in the home. Light-emitting diode senses the fire leakage in the home. The MQ-6 gas sensor senses the gas leakage in the home. These values are transferred to the LPC2148 microcontroller. The microcontroller has the inbuilt analog-to-digital converter(ADC) which converts the analog current and voltage values in digital form. These data are transferred by using GSM communication. This system controlling and monitoring electrical parameters of household appliances such as voltage, current, and power. This system controls the gas detection, fire detection, and motion detection. ARM processor used to control the device through the web page by using GSM communication.
Why: Problem statement
A smart grid is an electrical grid that uses the computer and other information technologies to gather and act in an automated fashion to improve the system’s reliability and efficiency. The smart grid enables information technology as a root to penetrate existing today’s electrical distribution system through information technology by using wireless sensor network. Smart Grid utility system encapsulates the net metering system for facilitating consumers to optimally utilize the power consumption. The gaining importance and urgency of an integrated smart grid monitoring system use wireless sensors network for advancements in the metering of the electrical meters to provide more efficiency, reliability, and options to the consumer. Smart meters’ Advanced Metering Infrastructure (AMI) provides an interface between the utility and its customers providing a bidirectional control mechanism, advanced functionalities, real-time electricity pricing, accurate load characterization, and outage detection or restoration. Wired sensor networks have already been reached and deployed in many applications over a decade, because of the wireless extension, smart grids have witnessed a tremendous upsurge in interest and activities in recent years. New technologies include cutting-edge advancements in information technology, sensors, metering, transmission, distribution, and electricity storage technology, as well as providing new information and flexibility to both consumers and providers of electricity. The GSM frequency bands or frequency ranges are the cellular frequencies designated by the ITU for the operation of GSM phones. The term GSM900 is used for a GSM system which operates in any 900 MHz, to help Japan create smart homes that improve energy management and efficiency. It is expected that 65 million households will equip with smart meters by 2015 and it is a realistic estimate of the size of the home energy management market. Smart Grid and wireless sensor networks provide intelligent functions that advance interactions of agents such as telecommunication, control, and optimization to achieve adaptability, self-healing, efficiency, cybersecurity, and reliability of power systems while reducing the cost and providing efficient resource management and utilization. To connect various domestic appliances and have wireless networks to monitor and control based on the effective power, tariffs have been proposed, but the prototypes are verified using testbed scenarios. Also, smart meter systems have been designed to specific usages particularly related to geographical usages and are limited to specific places. Different Information and Communication technologies integrating with smart meter devices have been proposed and tested at different flats in a residential area for optimal power utilization, but individual controlling of the devices are limited to specific houses. Considering performance and cost factors related to the design and development of smart meters and also predicting the usage of the power consumption have been demonstrated. However, a low-cost, flexible and robust system to continuously monitor and control based on consumer requirements at early stages of development.
How: Solution description
In this project, a low-cost, flexible and real-time smart power management system which can easily integrate with the home monitoring systems. The form of energy which involves the flow of electrons is called electricity. It is one of the most widely used forms of energy and plays a crucial role in the development of humankind. One of the most important are of electrical knowledge is the study of the electrical power system. Electric power systems are real-time energy delivery systems. They are not a storage system like water and gas systems. Electrical power systems have been in existence for many years. Alternating current (AC) power generation became widespread in the late nineteenth century. All the electrical power systems distribute three-phase alternating current. The primary sources for electricity generation are coal, gas, oil, nuclear power and other natural resources. At present, the customer and the utility companies have continuous concerns regarding the operational efficiency of the power distribution and associated systems have expanded rapidly since their development and continue to rise. Smart grids are applicable in the generation, transmission, and distribution. Generation of the electricity can be done by using renewable sources of energy like water, solar energy, and wind energy. On the transmission side, the smart grids are used in various applications like detecting a fault location automatically. The proposed method of this paper is mainly based on the consumer side such as monitoring and controlling load appliances wirelessly. The basic necessity for the application of a smart grid on the utility side has numerous reasons. At present, some electrical companies provide different tariff rates which vary throughout the day. Electricity is expensive during peak time and it is relevantly cheaper during off-peak time. The increasing demand for electricity will result in a significant change when the rates of electricity vary everywhere in the world. The main concern is maximizing consumption without paying heavier costs.
How is it different from competition
The home automation using the Internet of Things has been experimentally proven to work satisfactorily by connecting simple appliances to it and the appliances were successfully controlled remotely through the internet. The designed system not only monitors the sensor data, like temperature, gas, light, motion sensor but also actuates a process according to the requirement, for example switching on the light when it gets dark. It also stores the sensor parameters in the cloud (Gmail) promptly. This will help the user to analyze the condition of various parameters in the home anytime anywhere.
