  1. 1. Power Management System and Advance Metering with Integrated Renewable Energy Resources Lalit Kumar Prashant Kumar Student, M.TECH VLSI, AP, Electronics Engg. Dept. YMCAUST, Faridabad, YMCAUST Faridabad Haryana, India-121006 Haryana, India-121006 lalitsehrawat1000@gmail.com pk.vlsi@gmai.com Abstract—The idea of the present work is to use advance system to improve the power management and smart metering with integrated renewable energy resources. This Idea use renewable energy sources for example solar panel at home and street poles then by using smart metering system it canbe found how much power produced by the customer and how much extra used by him and accordingly the customer can be charged. Smart metering system use RF or IR or optical communication system to transfer data to the master meter reading instrument (MMRI) or meter reading instrument (MRI). MMRI and MRI use GSM to transfer data to the operator’s server and then received data is processed according to the requirement and this data can alsobe uploaded to the website used by the distributor,and further it can be used to send billing information to the customers.This study deals with the various advantages and disadvantages of implementation of this system. Keywords— MMRI; RF; power;GSM. I. INTRODUCTION This is an advance system to improve the power management and smart metering with integrated renewable energy resources. This Idea use renewable energy sources for example solar panel at home and street poles and collected the whole energy generated by this and power from the power station then by using smart metering system to find out how much power produced by the customer and how much extra consumed by him and accordingly can be charged from the customer Smart metering system use RF or IR or optical communication system to transfer data to the Master Meter Reading Instrument (MMRI) or Meter Reading Instrument (MRI). MMRI and MRI use GSM to transfer data to the operator’s server then received data is processed according to the requirement and then data also uploaded to the website used by the distributer. From the received data, Distributer can send SMS to the customer regarding their bill. He provides billing software for payment of bill. A. SMART METERING According to this idea, a RF, IR and optical communication media can be used for downloading the meter data from the customer meter, a RF communication mode can be used for the transfer of the more than 100 meters data with the help of Master meter reading instrument (MMRI) which is installed with the GSM Chip, which help in sending data the server. On server end assessment of that data can be done. This data can be formatted the particular way and further can be sent to a particular website so that everyone can see their electricity consumption and billing information. Implementation the billing software is done further so that customer can pay their bill online. From the server, data can be assessed to inform the customer about their bill through SMS to the registered mobile number of customer. Master Meter Reading Instrument (MMRI) can assess data from meter with the help of RF Communication at any free RF frequency band which is available and it can communicate with the help of hopping method up to 150 meter or more depends on the accuracy of the program and hardware. Fig.1 Smart Meter communication In the fig.1, it indicate the smart meter with the help MMRI and MRI can send data to the LAN from where Service provider can access the data. Service provider can format the data and send data to the website. Smart Meter with MMRI or MRI LAN Service Provider WAN Applications
  2. 2. MMRI send data in the packets so that if communication breaks then also it can send data after connection again establish. MMRI cannot send whole data at one time if connection break then whole data will be lost or corrupted. Each packet will be provided a unique number so that easy to recognize the accurate data with correct sequence. Meter can send the data to MMRI in packets so that every meter can get its chance to send its data. We can also send defecting or tempering of meter information to the MMRI so that tempering can be detected and proper action can be taken against that person for tempering of meter. By using this type of record maintaining service Provider can also analyze data so that they can find out the timing zone in a day for which power consumption is more for particular region so that they can increase power timing for that particular region. Fig.2 Block diagram of Power Management System with smart metering. In Fig.2 shows the whole Idea of the system, power from power grid and from renewable energy resources i.e. solar system collected at the power distribution station then collected power can be utilized in the effectively. Data from MMRI collected at the server end and after formatting properly that data can be utilized for all application purpose. Service provider can utilize that data for the improvement of the meter and other hardware without interfering the working of meter and customer by continues analyses of the data obtained from meter along with data billing information. Optical communication has less range as compared to IR and RF so it is optional if anyone want to use it. IR communication(760 nm wavelength) has approximately 1 or 2 meter range which can be extended for further improvement of our hardware. RF communication has about 100 to 200 meter range which can be extended by using hoping method in the RF communication. B. Master Meter Reading Instrument (MMRI) MMRI can be installed in the any location which is able to cover more meters in its RF range. MMRI has GSM module and RF communication circuit. It will be small device which can be powered by the small charger with the rechargeable Ni-Cd battery with long life. They can use GPRS system to it so that they can find out the exact location of MMRI and defected MMRI can also replace and can update its RTC (Real Time Clock). It can be installed in any pole above the head so that no one can harm to it. Service provider can use its protection from moisture, rain and dust etc. If data not send successfully then it can send data again. It will store data for one weak and in its memory and then after one weak it automatically erase its data after successfully uploaded on the related server so that need not much large amount of memory space. Service Provide can provide USB and UART communication port for manual downloading the MMRI and we can develop meter reading instrument (MRI) for the purpose of manual downloading of data with IR, RF and optical communication. II. BENEFITS A series of benefits includes the following • Man power reduced for maintaining record of each individual meter. • Transparency increase as all data uploaded on website so that everyone can see easily their data and billing regarding information. • It will increase the digitalization of metering system in India. • Reduced cost as service provider can access data about the defected meter remotely. • Customer friendly as they receive information through SMS and website also. • Human error can be avoided. • Demand and distribution management. • Accurate billing because inaccurate billing give difficult revenue planning.

  3. 3. • Intelligent building are not imaginable without smart metering devices • Customer reduces emission of CO2. • Can compensate the rate at the peak hour of consumption. • Load profile is the load record with time so that production company manage according to load. • 15 minute load profile so the maximum load used by customer can be detected. • It is very difficult to find fault in meter in the customer end by manually. • It is the two way communication and bidirectional flow of energy. • Better control of bulk generation. • Real time monitoring and control of power system reliability. • Expert from different domain need to be involved. • Cyber security and cloud computing bound to get increasing important. • On the spot billing using hand held system. • Increase use of renewable energy sources which have variable nature. • Employee safety assures. • Self-healing. III. SECURITY Service Provider should use encoding for communication so that unauthorized user cannot access the data and only specific software (used for that purpose) can access the data and it also cannot change the data. Specific server used for this purpose which is also password protected and used other security also. In this way they can get a much more secure system for this purpose. IV. CONCLUSION In this paper we have presenting the case that power management system with integrated renewable resources is under research. It poses many unique challenges and opportunity, e.g. interoperability, scalability, and security. The success of future power management depends heavily on the communication infrastructure, devices, and enabling services and software. Due to space limitations, there are a number of important issues we have not discussed here in detail, e.g. power saving technologies, distributed/centralized data processing, and infrastructure management. In particular, an exciting research challenge is how this power management system fits into the overall picture of the future Internet, currently under development. V. FUTURE SCOPE • By this method power supply automation can be done. • Home appliances can automatically controlled by using sensors. • Continuously analyze of system by using feedback from the installed remotely meter find the error and further improvement of the system. • Cost of installation and maintenance can be reduced drastically. • Renewable energy integration. • Awareness to the customer about new policy and rate of power system.
