Nanogrids, Microgrids, and Big Data: The Future of the Power Grid – IEEE Spectrum

 The power grid’s interlocking technological, economic, and regulatory underpinnings were established about a century ago and have undergone only minimal disruption in the decades since. But now the industry is facing massive change.

    Microgrid musings of an EE

    The US Department of Energy (DOE) defines a microgrid as a group of interconnected loads and distributed energy resources within clearly defined electrical boundaries that act as a single controllable entity with respect to the grid. It can connect and disconnect from the grid to enable it to operate in both grid-connected or island-mode

    Startup Profile: ME SOLshare’s “Swarm Electrification” Powers Villages in Bangladesh

    Bangladesh hosts the world’s largest collection of off-grid solar energy systems. Rooftop panels and batteries electrify over 4 million households and businesses there. The Dhaka-based startup ME SOLshare believes it has the technology to link these systems and foster a solar energy-sharing economy. If the company succeeds, home systems will morph into village minigrids, offering wider access to more power at lower cost.

    SOLshare’s European founders—Sebastian Groh, Hannes Kirchhoff, and Daniel Ciganovic—conceived their “swarm electrification” power-sharing platform during grad-school brainstorming sessions in Germany and California. The three moved to Dhaka to define, engineer, and launch their product, starting with power measurements in off-grid solar homes.

    A smart power controller, called a SOLbox, is installed in each home or business and linked with cables to other local SOLboxes to form a DC distribution grid. The SOLbox enables users to set how much power they want to share with or draw from the network, and at what price.

    The SOLbox handles the accounting, too, reconciling power purchases and sales—as well as SOLshare’s brokerage fee—via each user’s mobile money wallet. Wireless communications allow SOLshare to optimize power flows over the meshed DC grids to minimize bottlenecks and line losses.
