Technical Challenges in Smart Grid

Real Time State Estimation and Smart Grid.

This article provides a survey on state estimation
(SE) in electric power grids and examines the
impact on SE of the technological changes being
proposed as a part of the smart grid development.
Although SE at the transmission level has
a long history, further research and development of innovative
SE schemes, including those for distribution systems, are
needed to meet the new challenges presented by the requirements
of the future grid. This article also presents some example
topics that signal processing (SP) research can contribute to
help meet those challenges.


Since the pioneering work of F.C. Schweppe in 1970 [1], SE has become a
key function in supervisory control and planning of electric power grids. It
serves to monitor the state of the grid and enables energy management systems
(EMS) to perform various important control and planning tasks such as establishing near
real-time network models for the grid, optimizing power flows, and bad data detection/analysis (see, e.g., [2] and [3]
and the references therein). Another example of the utility of SE is the SE-based reliability/security assessment
deployed to analyze contingencies and determine necessary corrective actions against possible failures in the power
In view of the ongoing development of a smarter grid, more research on SE is needed to meet the challenges that the
envisioned smart grid functionalities present. Among others, environmental compliance, energy conservation, and
improved dependability, reliability, and security will impose additional constraints on SE and require improved performance
in terms of response time and robustness [4]. In this article, we provide a brief survey of some SE technologies
developed over the last four decades and examine the challenges and opportunities presented by the evolution of the legacy
grid into a smarter grid, within a framework relevant to SP research.


SE is a fundamental functionality to ensure smooth, reliable and
secure operation of power grids. At the transmission level and,
particularly in the context of static estimation, SE has a rich history.
New developments that are in the offering for the smart
grid render such existing methods inadequate. Of particular
interest are the challenges introduced by new metering infrastructure
such as PMUs, variable and distributed sources including
renewables, and structural changes resulting from
integration of microgrids. The demands on SE are also much
more stringent now and concerns such as reliability, dependability,
security, and distributed nature and dynamic SE necessitate a
paradigm shift from the existing algorithms. The SP community
has much to offer in meeting these exciting challenges.

Economic Crisis and Software Industry

Economic Crisis and Software Industry



The impact of Global Economic Meltdown will have couple of very significant effect on the It and software Industry:

1.0 More Telecommuting and VPN will be embraced.

2.0 Managed Services will be wide spread

3.0 More Software Development will be outsourced.

4.0 More Technical Jobs will move to India/China.

5.0 Web 2.0 will be embraced aggressively


I think the middle management in Post industrial economy will be brutally reduced.



These are my personal opinion.
