Role of the Smart Grid in Facilitating the Integration of Renewables
Role of the Smart Grid in Facilitating the Integration of Renewables
With the focus on environmental sustainability and energy security, power system planners are looking at renewable energy as supplements and alternatives. But such generation sources have their own challenges - primarily intermittency. It is expected that the smart grid – due to its inherent communication, sensing and control capabilities – will have the ability to manage the load, storage and generation assets (including renewables) in the power grid to enable a large-scale integration of distributed generation. In a smart grid, information about the state of the grid and its components can be exchanged quickly over long distances and complex networks. It will therefore be possible to have the integration of sustainable energy sources, such as wind, solar, off-shore electricity, etc. for smoother system operation. But in order for this to be possible, the electric utility will have to evolve, and change their ways of operation to become an intelligent provider of these services. This lecture introduces the operational characteristics of renewable energy sources, and various aspects of the smart grid - technology, standards and regulations. It also addresses the interplay among distributed generation, storage and conventional generation to provide an efficient operational strategy in the context of the smart grid.

IEEE COMSOC CHAPTER TECHNICAL TALK – The ABCs of Orthogonal Frequency Division Multiplexing (OFDM) Part I
IEEE COMSOC CHAPTER TECHNICAL TALK – The ABCs of Orthogonal Frequency Division Multiplexing (OFDM) Part I
This is Part I of a Two Part Talk on OFDM. The abstract below is for both Part I and II: The main benefit of OFDM is its ability to cope with severe multipath channel conditions without the need for complex equalization filters. How does it accomplish this? The short answer: by "dividing and conquering." It partitions a high-data-rate signal into smaller low-data-rate signals so that the data can be sent over many low-rate sub-channels. The Time/Frequency relationships are presented with a figure that facilitates a straightforward understanding of the OFDM partitioning process. We emphasize the important role of the cyclic prefix (CP). We show how it allows us to change linear convolution into circular convolution, thereby purging any transients, which helps to maintain waveform orthogonality at the receiver. OFDM waveform synthesis is covered in detail. Also, the spectral properties of Real and Imaginary signals are reviewed. We further consider the peak-to-average power ratio (PAPR) in OFDM, and how the desire for small PAPR has given rise to a special variant of OFDM called single-carrier OFDM (SC-OFDM). Finally, we illustrate applications of this elegant technology in standards such as 802.11 and LTE.
