With increase in social awareness for energy saving many plant companies as well other large power users are expanding their use of distributed power systems which depends on renewable as well as other natural source of energies. In this large power system energy management system plays an important role for which higher energy utilization is required. Based on this, Sumitomo Electric has developed sEMSA, a new energy management system expected to reduce environmental loads while helping ot minimize energy costs. The new system meets a wide variety of customers’ needs such as utility companies. It offers a quick demand response (DR) helping to achieve smaller power cost prediction error as well as managing the power system on a real-time basis. Read more
DENSO and Nagoya University have jointly developed in-vehicle battery based energy management system (EMS) capable of efficiently controlling the charging and discharging of in-vehicle batteries based on forecasting models of household electricity demand and vehicle use. The EMS basically coordinates with batteries used in electric and plug-in hybrid vehicles to use their stored electricity to help keep down electricity bills. The system measures power consumption, the amount of power generated by solar panels, vehicle use as well as other household characteristics to construct models for forecasting household electricity demand and vehicle use.

Development of Megawatt-Class Electric Power Generation and Storage System with World’s Largest Redox Flow Battery
Sumitomo Electric Industries has successfully developed a megawatt-class electric power generation/storage system which consists of the world’s largest redox flow battery and Japan’s largest concentrator photovoltaic (CPV) units. Sumitomo is planning to demonstrate the megawatt-class system on the premises of the Yokohama Works (Sakae-Ku Yokohama) in July 2012. The system is comprised of 28 CPV units with maximum total power generation of 200 kW as its energy source and one redox flow battery with capacity of 1MW x 5 hours as a storage facility of CPV-generated power. By employing the EMS (Energy Management System) , the system is indented to regulate the amount of electricity provided by power companies using the redox flow battery’s charge/discharge control function.

Undoubtedly, sensor technology is playing a major role in realization of next generation of “Smart Homes”. The technology is foreseen as the basis for supporting the construction of home automation as well as Energy Management System (EMS). One of the companies who has been at forefront of this vision is Murata who just recently announced the development of sensor network system for smart homes which is capable of gathering information that has been detected by sensors via the ZigBee based Gateways, where it can transmit the gathered information via WiFi or Ethernet over the internet or to a tablet terminal. The system uses the Android-based controller. The new system is to perform detail control of lighting and air conditioning while monitoring power usage and environmental conditions such as temperature, humidity and lighting by using the sensors that are located throughout the home. In addition to this, as part of company’s effort in supporting the elderly in achieving a safe, peaceful and comfortable living environment, the network is capable of remote monitoring and preventing such incidents as heatstroke. The system provide a less environmental impact by combining energy harvesting technology and wireless communication with low current consumption.
