Power System Flexibility to Support Integration of Large-Scale Renewable Energy

Globally, it is needed to reduce greenhouse gas emissions to virtually zero by 2050, and the world is now entering an era of large-scale renewable energy integration. Especially, it is said that the share of solar photovoltaic power generation and wind power generation, whose power output fluctuates depending on the weather, also known as variable renewable energies (VREs), to the world power generation composition is about 10% at present and will turn to be about 70% as of 2050 (IEA, 2021).

To realize large-scale integration of such VREs, it is necessary to improve "flexibility" in power systems safely, stably, and economically, and its importance is recognized worldwide, including the 12th Clean Energy Ministerial (CEM) held in June 2021. In order to increase power system flexibility, various studies and projects are being conducted, from power generation and transmission levels to distribution levels worldwide with information technologies (IT), including maximum utilization of existing equipment, improvement of output prediction accuracy of VREs, control for VRE outputs, smart inverter (virtual inertia), energy storage, demand side management with electric vehicles and heat pumps and voltage concentration/coordinated control.

Therefore, this summit will be held under the theme of "Power System Flexibility to Support Integration of Large-Scale Renewable Energy", and leading experts from Japan and abroad will hold lectures on the current state of the power system, the problems to be solved and the required power system flexibility.
