  • Latest in Smart Grid projects are emerging as the biggest issue that smart meter should meet the security goal and the SW upgrade for compliance with future standard. However, unlike regular equipment, Smart meters should be designed in accordance with the regulation of legal metrology instrument in order to establish a fair trade-based business and unauthorized changes, it is not allowed and it is strictly limited by law. Therefore, this paper propose a new scheme of certification regarding type approval and verification for legal smart meter as analyzing the requirements of a smart meter regarding upgrade and security. This analysis shows that the proposed scheme comply with the regulation and the specification of smart meter by applying it to smart meter with smart card.

  • Electronic watt hour meters(WHM) for high pressure running in domestic were installed to the digital type meter and ones for low pressure are expected to complete within several years. Domestic power metering technology is being beyond a simple framework with an electronic type and is rapidly evolving to intelligent smart metering systems in conjunction with promotion of a national smart grid project. Major policy outlook of the world's major power company regarding Intelligent metering is the application of the fare structure diversification and is the improvement of level of service to customers. In addition, electric power companies should focus on the cost reduction and the improvement of management efficiency through an efficient operation of distribution facility. In this paper, we are about to make an observation of the additional services technology development trend of the overseas smart meter and to have a view of value-added services(VAS) system of smart meter suitable for the domestic environment based on the technology development of VAS utilizing electronic watt hour meter performed by recent research projects.

  • In this paper, a smart meter applying the international communication protocols has been developed. A smart meter requires communication protocols for two-way communication and control technology, registration and deregistration of electronic devices between electric power suppliers to exchange data. Standardization for communication protocols of a smart meter has been proceeding both in the US and Europe. The smart meter developed in this paper applied ANSI C12.22 as a communication protocol which is a north american standard. A smart meter should also provide the electric consuming information and electricity charge information to the customer in real time. Thus, the customer can behave the demand response based on this information. In this paper, the measured electricity from the smart meter is reported to the customer, and IHD(In Home Display) implemented with the windows software presents the reported real time data.

  • The collection and analysis of power information in the smart grid is essential. The collected utilize power information can be used to efficiently utilize power such as power generation and distribution. The role of smart meters communication through wire and wireless cable is important for collecting power information. Recently, many countries around the world are establishing international standards or unique standards of smart meter communication for power information collection of many smart meters. Thus, this paper investigates smart meter related papers and materials, and summarizes international and national standards for smart meter communication.

  • Smart grid system has been deployed fast despite of legal, business and technology problems in many countries. One important problem in deploying the smart grid system is to protect private smart meter readings from the unbelievable parties while the major smart meter functions are untouched. Privacy-preserving involves some challenges such as hardware limitations, secure cryptographic schemes and secure signal processing. In this paper, we focused particularly on the smart meter reading aggregation,which is the major research field in the smart meter privacy-preserving. We suggest a noisy weighted aggregation scheme to guarantee differential privacy. The noisy weighted values are generated in such a way that their product is one and are used for making the veiled measurements. In case that a Diffie-Hellman generator is applied to obtain the noisy weighted values, the noisy values are transformed in such a way that their sum is zero. The advantage of Diffie and Hellman group is usually to use 512 bits. Thus, compared to Paillier cryptosystem series which relies on very large key sizes, a significant performance can be obtained.

  • We see an energy fucused smart city evolution of the UK along with the project of "Smart London Plan (SLP)." A theoretical logic of business model innovation has been discussed and a research framework of evolving energy focused smart city is formulated. The starting point is the silo system. In the second stage, the private investment in smart meters establishes a basement for next stages. As results, the UK's smart energy sector has evolved from smart meter installation through smart grid to new business models such as water-energy nexus and microgrid. Before smart meter installation of the government, the electricity system was centralized. However, after consumer engagement plan has been set to make them understand benefits that they can secure through smart meters, the customer behavior has been changed. The data analytics firm enables greater understanding of consumer behavior and it helps energy industry to be smart via controlling, securing and using that data to improve the energy system. In the third stage, distribution network operators (DNOs)' access to smart meter data has been allowed and the segmentation starts. In the fourth stage, with collaboration of Ofwat and Ofgem, it is possible to eliminate unnecessary duplication of works and reduce interest conflict between water and electricity. In the fifth stage, smart meter and grid has been integrated as an "adaptive" system and a transition from DNO to DSO is accomplished for the integrated operation. Microgrid is a prototype for an "adaptive" smart grid. Previous steps enable London to accomplish a platform leadership to support the increasing electrification of the heating and transport sector and smart home.

  • In this paper, We implement a power-saving and efficient measures in buildings using the smart-meter. In order to save electric power energy, We propose an improved automatic power-factor controller(APFC) and demand control measures. This is achieved by controlling directly circuit breakers and the capacitor bank feeders in real time via a two-way smart-meter's ICT skills. Improved APFC is minimizing installation costs by series-parallel connecting heterologous capacitors to form a more diverse capacitor banking and controlling using the smart-meter. In order to suppress the demand power, We have designed a smart-meter with communication functions using Atmel's AVR465 and tested an operated lodging building for 24-hours. As a result, We made sure to always retained more than 95% power factor and did not occur over compensation.

  • Advanced Metering Infrastructure (AMI) is one of the important components to form a smart-gird, which is an advanced power system by combining the power system with the communication systems. This AMI makes it possible to exchange information between operators and consumers for the efficient and reliable operation of the power system through a smart meter or a In-Home Display. However, according to the increase of the demanded information such as the power quality, the accurate load-profile, and the billing data to help customers manage their power consumption, it is necessary to gather more accurate analytical data from each house appliances and transfer it to the smart meter for synthesizing the information and controlling each loads. In this paper, the development of the wireless data acquisition device for the individual load data metering, which is connected with the smart meter for advanced functions, is proposed. AVR, a kind of microcontroller, and Bluetooth are used and integrated into the proposed the wireless data acquisition device to transmit the detailed power data (voltage and current) to the smart meter. To verify the effectiveness of the proposed system, a hardware experiment is carried out including the confirmation of the possibility for providing the more various information by applying analysis algorithms to the obtained data. Also, the application structure of the wireless data acquisition device to gather the data from the various house appliances is presented.
