37、, gas, water and other meters, which may bring about the end of estimated bills and meter readings, and provide customers and energy distributors and suppliers with accurate information on the amount of a utility that is being used. Smart metering provides: customers with the information they requir

38、e to become energy savvy and make smarter decisions about their energy usage; energy suppliers with the means to better understand and service their customers; distributors with an effective tool to better monitor and manage their networks. In addition, smart metering enables those customers who cho

39、ose to generate their own electricity (micro-generators) to be financially rewarded for their contribution to the national grid, and for distributors to better manage this contribution b-ETSI TR 102 691. Smart metering may be regarded as one of the key technologies for smart grid systems. Rec. ITU-T

40、 F.747.1 (06/2012) 3 6.1 Smart grids and smart metering A smart grid is a type of electrical grid that attempts to predict and intelligently respond to the behaviour and actions of all electric power users connected to it suppliers, consumers and those that do both in order to efficiently deliver re

41、liable, economic and sustainable electricity services including: enhancement of reliability reducing peak demand shifting usage to off-peak hours lower total energy consumption actively managing electricity charging actively managing other usage to respond to other renewable resources. Smart grid te

42、chnologies have already been used in other applications, such as manufacturing and telecommunications. In general, smart grid technology may be divided into seven areas: integrated communications, sensing and measurement, smart metering, advanced components, advanced control, improved interfaces and

43、 decision support, and smart power generation. In other words, smart meters are key components of smart grids and consequently, smart metering is one of the crucial features for smart grids. 4 Rec.

47、7.1 (06/2012) 5 6.2 Technical overview of smart metering It is not only governments and utility companies, such as electricity, gas and water suppliers, but also researchers, that have been interested in automatic meter reading based on communication systems. Examples of smart metering benefits to c

48、ustomers, governments and utility companies are: lower metering cost energy savings for residential consumers reliability of supply various pricing schemes to attract new costumers easier detection of fraud and of outages automated billing. Smart metering comprises metering and exchange of meter inf

49、ormation between smart meters and utility companies. Various technologies can be used for metering and exchanging meter information. For example, power-line communications have been used for delivering electricity power to consumers and for transmitting gas and water measurements to utility providers. Alternatively, mobile networks can be used for exchanging messages in an automatic meter reading system. Sensor network technologies may be used for metering and collecting informati
