SYNOPSIS

In Japan, large penetration of distributed generations with renewable energy (RE) sources such as photovoltaic (PV) power generations and wind power generations, are growing due to government policies which are towards construction of low carbon society aiming at a sustainable society. Since the introduction of the RPS system in 2003, electric power supply from RE has doubled. Moreover, since the surplus electricity purchase system was introduced in 2009, the introduction of residential photovoltaic power generation has largely increased. Although these RE sources are free from exhaustion and do not generate greenhouse gas emissions at time of power generation, some of RE sources have demerits such as output power instability by weather conditions and difficulty of output power forecast. With large penetration of such variable output sources, it will be difficult to maintain supply and demand balance in a total power system. Due to these backgrounds, to have large integration of RE sources, it is required to create evolution in today’s power systems. They must be changed to smarter power systems, where Information and Communication Technology (ICT) is utilised for cooperation of power apparatus and a total optimization is aimed such as minimizing total society cost. Microgrid is a concept of local power and energy supply system using distributed energy resources (DERs) such as distributed generation and energy storage to enable energy efficiency improvement, local generation/consumption, supply reliability improvement, harmonization between distributed generations and bulk system, etc. For these purposes, energy storage system (ESS) such as battery system takes important roles due to its quick response. However, the largest disadvantage of battery system is its expensive installation cost. In this sense, the alternative solution for ESS have been discussed. In this workshop, two interesting demonstrations using hydrogen production process and power to heat (P2H) technologies will be introduced.

IEM Electrical Engineering Technical Division, Electronic Engineering Technical Division & the Institute of Electrical Engineers of Japan have organised “Half Day Workshop On Energy Storage Applications In Smart Power Systems” which will focus on informing participants on the knowledge of realisation of a low carbon society, smart grid power system’s reliability, and energy storage applications.
