Software evaluation of smart meters within a Legal Metrology perspective: A Brazilian case

2010 IEEE PES Innovative Smart Grid Technologies Conference Europe (ISGT Europe), 2010

Induced by a very unfavorable scenario of nontechnical losses (electricity theft), some electrical distribution companies in Brazil have moved from the traditional one meter per residence measurement process to a centralized multiresidences meter with two-way communication features, enabling both automatic reads and remote connect/disconnect of energy supplies. Those improvements can be seen as a natural transition toward an effective Smart grid, and have brought together the needs of a deep revision on regulatory procedures for the electrical meters evaluation conducted by the Brazilian Metrology Office. This paper shows that the increasing complexity from those new electrical grid equipments, particularly conveyed by additional software procedures, is a major issue and needs to be rapidly assimilated by metrological controls to avoid the appearance of stepping stones in the smart grid pathway. This paper aims to describe the whole set of relevant aspects revealed in this particular Brazilian experience, discussing the real scene and the respective challenges opposed.

South East Europe style smart metering: the cost effective solution for an ageing network

22nd International Conference and Exhibition on Electricity Distribution (CIRED 2013), 2013

Among the utilities of the SouthEast Europe Area, EPCG will be the first to deploy a fully operated smart metering system, covering more than 80% of its Customers in a few years. The deployment of a smart metering project may ensure several benefits for the Distribution Utility, for the Customers and for the whole Electrical Power System. DSO will improve economic and financial performance by reduction of losses, optimization of field operations and improvement / stabilization of credit collection. Consumers will have better services with quicker contract activation, deactivation and modification; thus, their relationship with the DSO will be improved by the diffused availability of information on outages, quality of supply and consumptions. Moreover, detailed information coming from the smart metering will enhance Consumers' awareness about energy utilization, thus contributing to optimization of energy consumption and economic benefits. A smart metering deployment, once chosen a reliable, "field proven" technology, also involves a strong logistic activity, requiring a jointly coordinated action of the several stakeholders involved within. Finally the head-end system and the meters should be designed to deliver a fine tuned set of functionalities. All these actions, solutions and functionalities are implemented to reach given profitability targets and facing existing problems such as technical and non-technical losses. EPCG, with the contribution of all the involved Suppliers, has been designing and setting up a sustainable and standardized smart metering solution, in order to achieve not only the aforementioned traditional benefits, but also concrete answers to the Montenegrin grid specific needs, arising from ageing and low performance.

Smart Grid Implementation in Brazil Must Focus on Consumer Behavior and Markets, Regulation, and Energetic Mix Availability

Smart Metering Technology and Services - Inspirations for Energy Utilities, 2016

In Brazil, although some critical components are already monitored, such as interface audit meters as well as large customers meters, the data analyses are not systematic nor in real time for all dealers. In the best of cases, when some kind of accounting science is applied to this information, this knowledge becomes sectored and used to support a business segment. Therefore, sensing, metering, data presentation, and their systematic usage, including simulation environment, tests, business intelligence reports, and electricity quality, need a business (re)organization to go through this focus. An evaluation of the Brazilian market was done, considering the up-to-date international experiences and running local pilots, specially built to demonstrate the domestic consumption, as a case studies, and the required evolution of systems and strategies to move on to this historical moment of development and reorganization of the energy market as well as the legislation/regulation. Metering possibilities are presented to improve smart grid implementation goals, recognizing customers' profiles, promoting innovative products and business.

The Implementation of Smart Metering Systems for Electricity Consumption in Croatia

The smart metering system is used for the remote measurement of measurands for a purpose of billing, and to process and transmit measurement results. Generation and transmission of measurement information by electric impulses has already been used at summarizing billing meters where the base meter is equipped with the impulses generator which directly or indirectly emits impulse to a master summarizing meter. The application of more developed remote meter reading systems has intensified in the last decade of previous century. Today, most of distribution companies in Europe use remote meter reading systems to read the electricity consumption of industrial facilities on medium and high voltage level of distribution. The smart metering system allows continuous reading and recording of many measurands, e.g. power quality and load curve, as well as early-stage failure detection, monitoring of the meter lid opening alarm (detection of unlicensed actions), detection of the opposite energy flow and many other appropriate signals. The advantage of these systems, besides the remote reading, is the possibility to control and set-up the parameters of the system without sending a human to the location. All mentioned induces the long-term reduction in financial expenses for the distribution system operator. The most common communication systems for information and control signals transmission are GSM (Global System Mobile) and PLC (Power Line Carrier). PLC is prevailing lately due to its smaller cost and independence of the GSM operator. The PLC technology is mostly used to the closest distribution transformer station, from where information is carried to the rest of the system by optic cables. The primary constraint on application of described systems is cost reduction and reaching reasonable cost effectiveness.

Comparison of life-cycle costs of energy metering processes

In this study, the basis of understanding and analyzing the business framework for measurement in competitive environment is created. Metering issues are currently discussed widely because investment decisions for automated meter reading (AMR) are currently under consideration in many European countries. The possibilities that new technology in the form of AMR offers can be studied more closely when cost structures of metering are more accurately known. In this study life cycle costs for 11 different kind of metering activities are presented. These are combination of 5 different Finnish distribution companies' alternatives to carry out energy measurement. Results show that the nature of metering processes varies according to the way they are carried out. Cost structures show also the parts of organization that put efforts on energy information creation. New technology in form of Automated Meter Reading (AMR) can change the business processes and work in general inside organizati...

A review on smart grids and experiences in Brazil

Renewable and Sustainable Energy Reviews, 2015

The paper presents a literature review on smart grid concepts, considering generation, transmission and distribution of electricity besides smart consumption, including smart home, Demand-Side Response Programs, and Active Demand-Side Management. An analysis of the smart grid development in Brazil is performed, presenting the policy and regulation efforts beyond investments. This analysis takes account a pattern for smart grid development, and one may observe that Brazil is going towards a smart grid full implementation; however it could take decades and requires adjusts from govern, regulatory agency, utilities and consumers, and more investments. Moreover, some of the major smart grid projects in Brazil are presented, and their characteristics are compared considering the technologies used, location and electric utility goals. Depending on the electric utilities objectives, one may observe similarities and differences between concepts adopted and location of the Brazilian smart grid pilot projects. The first objective is the validation and replicability of the pilot project implemented; once, the project location is a sample of the utility's energy market or it is a particular area of interest, like an off-grid powered island with high environmental restrictions, for instance. The second objective is creating a model of sustainable smart grid with national visibility, once the project location is a touristic place. The conception of smart grid is aligned with sustainability, and it is a tendency in Brazil a massive entry of smart grid technologies in the next years.

Technical analysis of the impact of smart meters' battery useful life on the management of a service company

2018

The interest in tele-controlled meters (Smart Meter) derives from their diffusion, promoted by the European Union and regulated by law, in the industrial sector of utilities distribution (light, gas and water) with different power supply technologies. In the electricity sector, these are supplied by the mains, in the gas and water sector, it has focused on battery power, becoming the critical element for the reliability of meters. In this context, the following study aims to evaluate, through a case study, the economic impact caused by the early replacement of the battery pack or the entire meter, which causes an increase in operating and plant costs in addition to the non-amortization of the meters. The methodology adopted starts from the evaluation of the correlation between data transmission and battery discharge using deep learning. Afterwards, starting from the knowledge of the probability distribution function of the transmitted data for each connection, different consumption profiles were simulated with the Monte Carlo method to identify the remaining useful life of the batteries. The comparison of the estimated useful life with the nominal lifetime of the meter, which is required to manufacturers by tender specifications, made it possible to assess the economic impact of the extraordinary maintenance operations required. The results made it possible to evaluate the strategic importance of the meters' batteries, whose incorrect functioning has a strong influence on the entire company management.
