MART ENERGY

In recent years, the terms “Smart Energy” and “Smart Energy Systems” have been used to express an approach that reaches broader than the term “Smart grid”. Where Smart Grids focus primarily on the electricity sector, Smart Energy Systems take an integrated holistic focus on the inclusion of more sectors (electricity, heating, cooling, industry, buildings and transportation) and allows for the identification of more achievable and affordable solutions to the transformation into future renewable and sustainable energy solutions. This paper first makes a review of the scientific literature within the field. Thereafter it discusses the term Smart Energy Systems with regard to the issues of definition, identification of solutions, modelling, and integration of storage. The conclusion is that the Smart Energy System concept represents a scientific shift in paradigms away from single-sector thinking to a coherent energy systems understanding on how to benefit from the integration of all sectors and infrastructures.

  • Smart electricity Meters

    Smart electricity Meters

    Conventionally, meter readers must physically visit and read electricity meters every month. This brings the following challenges:

    • Manual meter reading lacks the accuracy and efficiency of IoT solutions, and the high labor costs are high. Metering data cannot be collected and analyzed in real time.

    • Traditional meter reading cannot enable prepayment or differentiated pricing. Bills can only be paid at official service centers. This decreases the efficiency of electricity fee collection.

    • Electricity theft cannot be prevented, and electrical data cannot be collected in real time to analyze line loss efficiently.

    To address these problems, we provide two solutions for the electric power industry:

    The PLC-IoT AMI Meter Reading Solution and the eLTE-IoT AMI Meter Reading Solution. The PLC-IoT AMI Meter Reading Solution uses wired technologies and is deployed when there are no restrictions on deployment costs. The eLTE-IoT AMI Meter Reading Solution uses wireless technologies and is widely deployed when meters are distributed or urban renewal is ongoing.

    The PLC-IoT AMI Meter Reading Solution makes use of broadband Hi-PLC meter reading technology, which features a data rate 20 times higher than that of narrowband Power Line Communication (PLC) meter reading technology. This solution provides broadband over power lines (BPL) communications, ensuring a 100% meter reading success rate. This enables real-time bi-directional communications for meter reading and meets requirements of the future smart grid for metering data collection and electricity fee control.

    This solution provides online self-help services by providing customers with household or industry smart prepaid electricity meters. With these smart meters in place, users receive an email or a text notification several days before the bill is due. Electric utilities can provide customers with detailed electricity bills. Users can pay the bills through rechargeable cards, automatic payment machines, and service centers. This way, electricity fee collection is accelerated by two or three months.

    The AMI system can also provide customers with a clear view of the transformers, power lines, and other aspects of the power distribution grid. This way, customers can identify the potential risks of the power grid in time. When the power grid has exceptions, such as transformer overloading, theft of electricity, or electric leakage, alarms are automatically generated. The electric utilities can quickly locate problems, and dispatch staff to the right location to fix the problems. The comprehensive analysis helps identify exceptions, so as to reduce line loss by over 31% and prevent electricity theft.

  • Smart Gas Meters

    Smart Gas Meters

    The Smart Gas solution offers three major benefits. First, the solution enables real-time data backhaul and ensures safety. Data related to gas, such as device pressure and temperature, is transmitted to the management platform for real-time analysis. This facilitates preventive maintenance and eliminates safety hazards. Second, automatic meter reading helps residents avoid disturbances caused by manual meter reading and difficulties in bill payments. This adds further convenience to people's lives and reduces overall user complaints. Third, new profit models are derived from the development of smart gas. For example, residents can ensure the timely payment of property management fees through a purpose-built in-house smart gas mobile app.

    The development of smart gas services had for many years been restricted by traditional two-hop network communications technologies such as Long Range (LoRa) and RF networks. Network construction is particularly quite difficult to accomplish using traditional technologies. For example, concentrators can only be deployed after site selection, electricity connection, and network planning. Different locations and scenarios cannot use the same solution. Network construction often requires a long period of time. In addition, concentrators tend to suffer from an inability to withstand extreme weather conditions such as lightning, rain, or snow. As a direct result, concentrators may require frequent maintenance. For example, connection of mains electricity may be affected by man-made faults, and accidental solar power supply faults may occur due to heavy snow. Furthermore, LoRa and RF networks operate on unlicensed spectrum. Networks used by different applications, such as natural gas, water, street lamps, and parking, often experience co-channel interference. And it is difficult to coordinate all walks of life to help eliminate this problem.

    NB-IoT offers deep coverage and massive connections with low power consumption. It is an ideal network communications technology for the smart gas solution.

    Inherited networks: The NB-IoT Smart Gas Solution runs on operator networks upgraded from the existing 2G, 3G, and 4G networks. Gas meter vendors and natural gas utilities save considerable amounts of time and money required for network construction.

    Maintenance free: The NB-IoT network can be smoothly upgraded to 5G and is maintained by industry specialists from operators.

    Highly reliable: The NB-IoT network uses licensed spectrum and suffers from low interference. The solution can achieve a meter reading success rate of over 99%.

    The NB-IoT Smart Gas Solution helps natural gas utilities achieve preventive maintenance, provide convenient services, and increase profits. The solution enables the large-scale rapid growth of smart gas services.

     
  • Smart Heat Meters

    Smart Heat Meters

    In times of increasing energy costs, it is important to measure and control energy consumption accurately. We meet our customers' requirements by offering a variety of highly advanced, tailor-made heat and cooling metering solutions according to standards.

    Heat is measured with heat allocation meters or heat meters. Heat meters are used to measure the physical flow of energy used for heating, for example in apartments with underfloor heating systems. The installation of heat meters can also be recommended for metering the energy consumption of different user groups in one building (e.g. shops and apartments).

    Smart metering benefits utilities by improving customer satisfaction with faster interaction, while giving consumers more control of their energy usage to save money and reduce carbon emissions. With power visibility all the way to the meter, utilities can optimize energy distribution and even take action to shift demand loads.

    Smart metering helps utilities to:

    • Reduce operating expenses by managing manual operations remotely
    • Improve forecasting and streamline power-consumption
    • Improve customer service through profiling and segmentation
    • Reduce energy theft 
    • Simplify micro-generation monitoring and track renewable power 

    In addition, Smart Meters can enable an array of new smart services to residential, commercial, and industrial customers to better manage their energy usage patterns, reduce overall power consumption and even benefit from new pricing models.

     

    Cellular communications provide a reliable connectivity option for smart metering infrastructure, including full IP infrastructure and low latency in 4G LTE. With the ubiquitous reach of modern cellular networks, and the development of LTE-M (LTE for M2M) providing long range low power cost effective solutions, utilities can connect meters easily and inexpensively virtually anywhere. And they can benefit from a proven, highly reliable communications infrastructure without taking on the costs of deploying and maintaining it themselves. 

  • Smart Water Meters

    Smart Water Meters

    The Smart Water Solution offers three major benefits. First, the solution adopts a grid-based water meter system, monitors the pipeline network in real time, and rapidly locates pipeline failures to enable leakage analysis. Thanks to this solution, the rate of water leakage can be reduced. Second, users often complain about disturbances caused by manual meter reading or inaccurate manual estimation. Automatic meter reading effectively solves all these issues, helping to reduce user complaints and improve service quality. Third, this solution enables real-time data backhaul. Data related to water, such as quality, pressure, and temperature, can be managed elaborately and visually to enhance the capabilities of water utilities.

    The development of smart water services had for many years been restricted by traditional two-hop network communications technologies such as Long Range (LoRa) and RF networks. Network construction is particularly quite difficult to accomplish using traditional technologies. For example, concentrators can only be deployed after site selection, electricity connection, and network planning. Different locations and scenarios cannot use the same solution.
