Next-Generation Power Network Stabilization Technology Development for Large-Scale Integration of Renewable Energies

Project overview

Project period: FY2019 to FY2023, FY2019 budget: JPY 1.45 billion

In order to expand the introduction of renewable energy, such as solar and wind power generation, whose power generating capacity is affected by the weather and similar factors, it is necessary to significantly enhance power systems within the framework of conventional technology and systems. However, such efforts are not at all easy because they are expensive and securing the necessary land is time-consuming.

One goal of this project is to maximize the utilization of existing grid systems by developing prediction and control systems for individual grid systems aimed at the achievement of non-firm connections* at an early stage. Another goal of the project is to develop optimal systems control technology in order to resolve various issues & mdash;including fluctuations in voltage and flow of power distribution systems & mdash;to work toward the establishment of distributed network systems.

*Non-firm connection:
a method that makes it possible to connect a new power source to the grid, subject to controlling its output, when the power grid is congested by other power sources in operation.

  • Development of control units that realize Japanese-style “connect & manage” grid Development of basic technology to cope with decreases in inertia Wide-area data collection Development of optimal methods for controlling voltage and power flow in power distribution systems Power distribution network Development of optimal islanding detection method for power conditioning subsystems to prevent voltage flickering in high voltage grid-connected operations Utilization of functions for smart inverters
