Challenges & Solutions

  • Smart Grid Challenges

    The creation and management of a smart grid brings about several challenges that electric utilities must overcome, often with the help of their end users. Below are a few of the key challenges utilities face when implementing a smart grid.

    • Replace energy loss with battery energy storage: Electric power generation is relatively fixed and stable, but demand fluctuates. When energy produced is higher than demanded, the excess is lost. By storing energy, network operators can more easily balance electricity supply and demand by charging the battery when there is a surplus, and distributing the stored energy when there is a high demand (e.g. during winter months).This also allows individual users to participate by installing their own solar panels and storing energy to sell back to the operator or using it themselves.
    • Energy and environmental efficiency: Using energy efficiently enables operators to provide the same service, product and level of comfort with less energy, and also reduces cost and carbon dioxin emissions. Environmental efficiency takes into account the energy source and any negative environmental impacts (clean renewables versus fossil fuel that has limited supply and generates CO2, and nuclear that produces radioactive wastes). The equipment life cycle and environmental externalities can all be incredibly affected by the choices made.
    • Peak load management and peak shaving: Traditional generators have been used during peak energy periods because they can start quickly and require low initial investment. However, they are not efficient and contribute to high carbon content during peak energy usage. Demand response solutions help shift or eliminate energy peaks, thereby reducing CO2 production and GHG emissions.
    • Renewable and distributed energy resources: Replacing fossil energy with renewable energy is a key challenge, hindered by the variability in wind and solar energy production and integration into the grid. However, as more renewable energy plants are integrated into the grid, the variability decreases and regular demand can be met.
    • Load leveling: Demand for electricity continually fluctuates based on the time of day, day of the week and the season, and energy suppliers must constantly adapt the production rates. By collecting data on the grid, smart management systems can forecast energy needs and allow suppliers to produce energy based on predicted usage.

    Solution Concepts

    In response to the challenges outlined above and spurred by technological advances, the utility industry has seen an increase in the number of concepts and solutions set forth to aid in the implementation and management of the smart grid.

    • Prosumer: A prosumer is simultaneously a consumer and a producer of electricity. Prosumers are new key actors of the grid, and contribute to grid reliability and renewable integration by managing their own production and consumption, and selling unused power back into the grid.
    • Demand response: Utilities traditionally match demand and supply by taking generating units on or off line, or importing power from other utilities. However, it can take a long time to come up to full power, the units may be expensive to operate, and demand may be greater than all the available power. Demand response seeks to adjust the demand for power instead of adjusting the supply, by moving some of the utility customer’s energy usage to off-peak hours.
    • Integrated Distribution Management System (IDMS): The smart grid gives distribution utilities access to information they never had before. This data often comes from a variety of equipment and resources that cannot communicate with each other. GE’s IDMS unites SCADA, DMS and OMS systems into one integrated platform that analyzes the information, significantly extending the capability of the local power grid and the dispatch of local energy resources.
    • City Energy Management System (CEMS): CEMS is a modular software platform that enables smart cities and territories to monitor, analyze and optimize their energy usage. It is a key decision support tool for the implementation and follow up of their own energy plans. Watch this video to learn more about smart cities.
    • Distributed Energy Resource Management System (DERMS): DERMS integrates all sources of “green” energy resources at the distribution grid level, allowing for a real time management of distributed renewables, storage demand response, smart buildings and electric vehicles. DERMS delivers a full range of environmental benefits, including integration of small-scale renewables, connection of smart buildings to the grid, management of energy storage systems to integrate more renewables and eliminate peaks, optimization of electric vehicle charging to minimize loading peaks and reduce GHG transportation emissions, and management of end-user consumption via demand response functions.
    • Demand Response Management System (DRMS): GE’s e-terra Demand Response System helps utilities better exchange with their end customers to reduce consumption peaks, avoid bottlenecks and optimize electricity dispatch.

Environmental Benefits

  • The cost of generating one kilowatt-hour (kWh) of electricity is 70-170 times more than the cost of “saving” a kWh through efficiency. GE’s smart grid technologies help reduce lost energy and cost, and at the same time enable a virtuous circle of environmental benefits.

    Improve energy efficiency:
        Lower delivery losses in transmission and distribution which enables consumers to use more of the power brought into the system.
        Anticipate and monitor demand to help minimize overcapacity.

    Optimize energy storage:
        Help network operators by storing energy so they can more easily balance electricity supply and demand from central and distributed energy resources.
        Optimize battery charging when there is a surplus of energy, and release the stored energy when there is a high demand (daily or seasonal peaks).

    Enable peak shaving:
        Reduce the peaks in demand for power to maximize the use of energy generated.
        Avoid investment in peak generators.
        Permit adaptation of energy usage times to meet energy production by using demand response.
        Disconnect microgrids from the centralized grid to operate autonomously, strengthen the grid resilience and help mitigate grid disturbances.
        GHG reduction resulting both from less peak generation (thermal) and from avoided investments (concrete from plant and transmission lines).

    Facilitate renewable integration:
        Optimize intermittent renewable energies by adding more clean wind, solar and biomass in the generation mix.
        Avoid investments in transmission and distribution network upgrades.

    Integrate local and domestic energy:
        Connect more domestic clean energy sources to the grid.
        Enable integration of new energy positive buildings.
        Lower reliance on the volatility of imported fuels and augment energy independence and security

    Facilitate eco citizen behaviors:
        Provide new opportunities for consumers to manage their electricity use, control costs and adapt wiser behavior in the use of energy through demand response.
        Empower users by providing solutions to connect individual energy production to the grid, where consumers not only buy and use energy, but can become producers as well (prosumers).
        Improve customer experience and security through education and communication from utilities to anticipate and prevent problems, and create sustainable relations between customers and the utility

    Reduce material labor and engineering needs:
        Save up to 15% costs with fewer wires and up to 50% with fewer panels for a smart grid installation.
        Sensors enable operators to be alerted before a machine fails and to save money by repairing rather than replacing.
        Solve problems with maintenance instead of repair - companies that employ proactive condition-based maintenance spend on average 2% of replacement asset value annually on maintenance while those that wait for equipment to fail spend an average of 13%.
        Maximize assets’ productive life cycles and reliability to reduce the need for new equipment.
