Ever since the Great East Japan Earthquake in 2011, conventional energy supply systems relying on large-scale power plants are being reevaluated, and distributed power sources, such as solar power, wind power, and other renewable energies, are becoming more widely used. Since the amount of power generated by renewable energies is affected by weather conditions, the energy supply becomes unstable as the use of renewable energies increases. The VPP (Virtual Power Plant) is a new energy service concept as a solution for maintaining balance in the energy grid. A VPP utilizes IoT-devices to remotely control distributed energy sources and energy storage to function as if it was a single power plant.
VPPs require real-time control of a large number of distributed power generation and storage facilities in response to ever-changing supply and demand conditions. VPPs will enable the stable use of renewable energy by adjusting the supply-demand balance, and will also promote the introduction and expansion of renewable energies and contribute to a decarbonized society.
