Smart Grids & Smart Community

Managing Energy Demand and Supply


Session background and objectives

・As a result of the massive introduction of renewable electricity generation and subsequent changes in generation and consumption structures, it is becoming increasingly important to develop managing technologies of demand control and grid system, as well as bring about the associated institutional reforms.

・In this session, future perspective of managing technologies of both hardware and control software, will be discussed in order to realize a low-carbon society and simultaneously maintain grid stability.

・Specifically, we will review the Internet of Things (IoT), big data technology, electricity market design, demand response, Vehicle-to-grid (V2G), and the potential of energy saving from consumers’ behavior change.

・Through discussions in this session, we will identify the progress and issues concerning technological innovation. Our discussions will be summarized as a session proposal for promoting future technology diffusion and realizing a low-carbon society utilizing these technologies.

Smart Energy: Challenges and Opportunities of IoT

The blazing development of sensors and “on line” intelligence allows to present real time information, perfect operations, predict to anticipate.
IoT increases performance visibility, and where the savings potential is. It allows energy to be managed in real time based on immediate data rather than historic patterns of energy use. It enables new energy services and Utilities business models.
The basic building blocks exist. Suitable Standards could pre-resolve the daunting complexity but multiple frameworks are under development.
A bigger challenge is the lack of openness to sharing data, and the need for a powerful governance for cybersecurity and privacy.

Utility 3.0: Roles of Future Utility Industries to Decarbonize the Society

Japanese utility industries are in the process of transformation triggered by deregulation, de-carbonization, decentralization, depopulation and digitalization.
Electrification of transportation and heat demand, and the utilization of the low carbon technologies such as highly efficient fossil generation, CCS, renewable resource, advanced nuclear and distributed energy storages would be the key technologies to realize decarbonize the society. The roles of the future utilities would be to provide the following integrated platform collaborated with other industry players.
- Energy system and market management,
- Integrated infrastructures (IT, transportation, gas, water and electricity),
- Data platform of sensing, measuring, analytics and billing

Case studies of resource aggregation, V2G (Vehicle-to-grid) and others

Less cost of PV and battery energy storage enables higher penetration of renewable energy and it resulted that some regions begin to change or discontinue their policy on incentives to PV dissemination while some activities try to transit to new energy system based on increasing needs from both of political and customer side.
NEDO has been promoting activities that try to overcome those issues by introducing Japanese technologies and systems including V2X through its oversea Smart Community demonstration program. This presentation will focus on discussing what's the next steps in this field based on current NEDO's activities.
