2 1. Background

3 What utility industry is facing Utilities see increasing need to monitor (and wish to control) output of Distributed Energy Resources (DER); solar panel, PHEV and energy storage at home. Utility has also need for monitoring (and appropriately) controlling home appliances for energy efficiency and demand response. These functionalities are provided by building Smart Grid and Home Area Network (HAN). However, building smart grid and HAN are very expensive.

4 What MESIA does? MESIA is Multi node Energy Sensor Interactive Architecture for utility to economically monitor energy data in home, and work with resident customer and/or a third party company to optimize use of Distributed Energy Resources (DEN; solar, PHEV, energy storage) and various home appliances in order to achieve energy efficiency and low carbon society. It s a broadband based Distributed Metering System.

7 Key features of MESIA Utility does not need to invest in expensive Smart Meters. Instead, utility does or let Energy Service Provider use many sets of Inexpensive power sensor devices to be attached at DER and home appliances for measuring and transmitting meter/output data. Utility will displace conventional meter with tiny chip (sensor device) to monitor amp, voltage, frequency, and maybe temperature directly or through a third party.. The sensor device will be secured and certified for meter quality. Utility can rely on data security.

8 Key features of MESIA Utility does not need to invest in expensive AMI and data center, and build (redundant) communication system to the meter. Instead, it can use available broadband communication capacity provided by telecom companies or cell phone carriers for meter and power output data delivery. Utility simply pays for the cost of (a portion of) using communication capacity and gateway use. Energy management service software is one of the applications to be downloaded to the gateway.

9 Sensor device just fit into circuit breaker The new power sensor device will be Installed in a size of single breaker socket so that it will fill in the box without retrofit. It includes communication platform. The device will be localized according to each specification and configuration requirement of circuit breaker.

10 Use of public broadband line and home gateway Wherever resident has existing broadband service, electric utility should use this capacity for energy data communication. If not, electric utility should collaborate with broadband carriers (phone company or cellular company) to encourage them to lay the line where electric utility could be a part of line capacity user as well as other service providers. For telecom companies, this will create a revenue opportunity in platform business, where they will provide multiple service gateway called OSGi, and collect fees from those who use it.

11 OSGi Framwork OSGi (Open Service Gateway initiative) is a middleware platform to be built in the gateway, to enable adding/changing service, data and functionality without interruption of operation.

13 Scalability of HEMS to Community Energy Management System (CEMS) MESIA will support utilities to better manage distribution network at a time of growing number of DER by balancing home energy use with generation. Each home is supplied with HEMS with energy and data storage. Customer and utility will reduce day time peak by automatically shutting off idle power by HEMS and cell phone control. For utility, there will be less reverse flow from this home, less need for balancing voltage shift.

14 Scalability of HEMS to Community Energy Management System (CEMS) MESIA will better perform when applied to community level, by balancing out generation and consumption of power and optimize storage within the area. (i.e., a neighbor with one person may have excess generation while others with multi family have short of power.) Locally generated and stored power will be used optimally so that there will be least need for utility power, generated from fossil fuel and transported in a distance with environment burden. This will lead to zero emission town and zero emission city.
