SEP 2 IP-based energy management for home


What exactly is smart energy profile (SEP 2) IP-based energy management for the home? Introducing the SEP 2, Tobin Richardson, chairman and CEO, ZigBee Alliance said ZigBee smart energy is the standard of choice for home area networks (HANs).

ZigBeeAbout 40+ million ZigBee electric meters are being deployed. ZigBee smart energy is being enhanced by network/communications options, support for forward-looking developments, etc. SEP 2 is a joint effort with the HomePlug Alliance. There is a vision of MAC/PHY agnostic SmartEnergy profile.

Robby Simpson, SEP 2 Technical Working Group Chair, system architect, GE Digital Energy, provided the features and benefits of Smart Energy. Features include price communication, demand response and load control, energy usage information/metering data, prepayment metering, text messaging, plug-in electric vehicles, distributed energy resources, billing communication, etc.

Example applications are many, such as smartphones, ESI in the sky, tablets, TVs, plug-in electric vehicles, PCs, solar inverters, thermostats, energy management systems, smart meters, building management systems, smart appliances, etc. There is support for a variety of architectures. The use of IP eases convergence and architecture changes. A consortium for SEP 2 interoperability (CSEP) has been established.

Skip Ashton, ZigBee Arch. review committee chair, senior apps director,  Silicon Labs said implementations of SEP 2 are available from a number of companies and across several MAC/PHYs. All standard documents are available for review.

Jeff Gooding, Southern California Edison (SCE), spoke about creating SEP 2 energy ecosysyems. SEP 2 can bridge multi-platform customer technologies to create a rich ecosystem. SEP 2 customer focused solutions can allow the utilities and energy service providers to use any customer communication channel. SEP 2 pilots at SCE include a gateway pilot and a smart charging pilot. Both are separate pilots.

Semicon industry at inflection point of innovation: Rich Beyer

Prior to this year’s FTF, Freescale marked another milestone in our company’s history. We have returned to the public trading arena with our IPO on May 26.  We used the proceeds from the IPO to pay down a portion of our debt and reduce our interest expense. This will enable Freescale to continue to grow our investments in products, software, sales and customer support. We are confident, as a result, we will continue to offer you even better world class solutions.

Having publicly traded stock will also give us more flexibility than just available cash to fund potential acquisitions and future innovation investments that will reinforce our competitive differentiation moving forward. And, the IPO is a strong affirmation that Freescale is on a very successful trajectory in the eyes of the investment community! While we have changed to become a publicly traded company, we have not changed our vision or our strategic focus. Our vision remains the same: we are committed to being the leader in embedded processing solutions.

We will continue to build on our market leadership positions by focusing on our core strengths: embedded processors, applications processors, microcontrollers and DSPs; RF, analog and sensors; and the software that delivers a clear competitive advantage to our customers.

Era of connected intelligence
Over the past several years, we have entered the era of connected intelligence where embedded processing is driving the Internet of Things. In the PC era of the past, processing was centralized within a traditional computing environment. Users relied heavily on computing hardware and rigid software to perform desired tasks.

In today’s era of connected intelligence, data is ubiquitous, and we expect our electronic devices to conform to us. We want them to be social and mobile. They are aware of our surroundings, and they understand and adapt to the context in which we are using them. They are always on and they are always with us.

Semiconductor innovation
We are at an inflection point in what is driving semiconductor innovation. In the PC era, the focus was on the sheer performance of the processor. The power consumption implications were handled by a building bigger box, adding a cooling fan or using a larger battery.

In the era of Connected Intelligence, embedded processing performance needs to be balanced with power efficiency, and system capability is enabled by the intelligent integration of sensor, RF and analog interfaces and the usage of efficient, system sparing software.

The insatiable demand for connectivity will continue to push the industry for solutions that deliver more performance, improved efficiency and lower operating costs. Semiconductor innovation now is being driven by embedded processing solutions with a system-level view and developed with an application-level expertise that is critical to efficient and timely implementation.

Strategic roadmap for electronics enabling energy efficient usage: Venkat Rajaraman, Su-Kam

September 16, 2010 1 comment

Venkat Rajaraman, CEO, Su-kam.

Venkat Rajaraman.

I am very grateful to Venkat Rajaraman, CEO, Su-kam Power Systems Ltd, for sharing his thoughts, as well as those of Dr. Ajay Mathur, director general, Bureau of Energy Efficiency (BEE), presented at the India Semiconductor Association’s (ISA) conference titled ‘Electronics enabling Energy Efficiency E3’, in New Delhi.

In his presentation, Rajaraman said that if Graham Bell were alive today, he won’t even recognize his invention. Mobile devices have changed, the switching technology is vastly different and so is the communication medium.

However, if Thomas Alva Edison were alive today, he would be very happy! He would see that his invention in pretty much the same form. Of course, there are more generating stations, more transmission and distribution lines, but the technology is fundamentally the same.

This scenario is quite changing. Yesterday’s era was all about industrialization – more automation, less labor, etc. Also, the more energy you consume, the lesser it costs to produce. Energy was considered inexhaustible then. Now, there is a paradigm shift. It is all about energy conservation! We know that the energy cost is rising and the resources are finite.

The energy industry will change more over the next 15 years than it has in the last 100! The decisions made now to the next few years will determine whether the transition is considered a success!

So, these changes are not about simple energy efficient appliances, smart meters, renewables, etc. It requires a complete socio-economic and mindset change, and that’s the hard part of the problem.

Rajaraman added that there seem to be far too many stakeholders in energy efficiency implementations — financial Institutions, technologies solution providers, beneficiary industries, energy audit companies, measurement and verification systems, government/subsidy bodies, etc.

A plant owner is not attracted enough to make the investment in energy efficiency. There are questions such as who will own the results, who will deliver it, how will it be delivered? Herein lies the problem and the opportunity!

There have been several interventions from the BEE. They have been attacking this problem from policy perspective in a clinical precision manner. BEE has been doing a great job in coming out with policies that comprehensively covers such issues.

Rajaraman concluded that simple technological and policy interventions alone are not going to be enough. It needs a social and mindset change. He concluded: “Give a man one CFL/LED, you secure one CFL/LED worth of energy savings! Teach a man to love his CFL/LED, you inspire a life time of energy efficient behavior!”

Su-Kam has been doing simple interventions regarding energy efficiency – such as, replacing DG sets with inverters, LED lighting, etc.

I will later add a separate post on Dr. Ajay Mathur’s thoughts.
