However, this process involves substantial costs and land acquisition, and takes a long time, making it a challenging task. In this project, to make the most of existing systems, NEDO will focus on the early realization of non-firm connections.* This involves the development of individual system prediction and control systems, as well as the development of optimal control technologies for addressing challenges such as voltage and power flow variations in the distribution system. Additionally, efforts will be directed toward establishing a decentralized network system. * Non-firm connection: A method that allows the connection of new power sources, assuming control of output during congested periods when other power sources are operational. Research and Development R&D Item [1]-I Developing Control System to Realize the Japanese Version of "Connect & Manage" NEDO will develop the control systems to realize Japanese version of “Connect & Manage," including "non-firm connections" which flexibly utilizes the available capacity of existing systems and allows connections to the system under certain conditions. R&D Item [1]-II Development of Foundational Technologies to Address the Decrease in Inertial Forces and Similar Factors NEDO aims to establish methodologies for understanding inertial forces and visualization-based operational techniques. NEDO will establish foundational technology for constructing a continuous monitoring system for system inertia using PMUs (Phasor Measurement Units). NEDO aims to establish new technology to ensure system inertia. NEDO will develop control devices with inherent inertial forces and establish foundational technology for their application to the power system. R&D Item [2]-I Development of the Optimal Control Method for Voltage and Power Flow in the Distribution System NEDO will develop power flow monitoring and voltage control technologies for the distribution system, considering future demand activation and the progress of self-consumption. NEDO will implement technology development to appropriately transmit information from the distribution system to the upper-level extra-high voltage system. R&D Item [2]-II Development of the Optimal Standalone Operation Detection Method for Voltage Flicker Countermeasures in High-voltage Interconnection PCS (Power Conditioning System) NEDO will implement the necessary technology development to avoid power quality issues such as voltage flicker and voltage imbalance while maintaining proper voltage in situation where a large amount of renewable energy is introduced into the distribution system.
