Although the regulatory structure for limiting emission of greenhouse gases is uncertain, limits will be in force soon. Infrastructure needs to implement those limits are technologies to remove most carbon from electric generation emissions, technologies to dispose of the carbon removed, sensing systems to monitor carbon emissions, and market or regulatory structures to implement the limits. Adaptation to climate change will require upgrades and capacity increases in existing transmission and distribution systems, and increased capacity in new systems. Increased use of renewable can reduce carbon emissions. Higher penetrations of intermittent renewable resources, wind and solar, will be allowed if storage is available to allow full dispatch of those generators. Infrastructure needs for energy storage are efficient and cost-competitive technologies to store electricity, power electronic interfaces between those dc technologies and the ac power system, and monitoring and control systems to control and dispatch the storage systems.

Outage management and reporting systems that have been installed in year's past continue to have more demands placed on them to deliver greater functionality in real-time and analytical contexts. PacifiCorp has leveraged its systems to deliver more responsive actions after outages take place at locations throughout its system, using a combination of reporting and graphics to target areas where prompt actions need to be taken.

This paper presents an implementation to alleviate the overload in the energy markets. The proposed alleviating overload (AOL) method is based on real time network analysis (RTNET), state estimator (SE), real time contingency analysis (RTCA), and the constraint shift factor (CSF) calculation in the energy management system (EMS). RTNET/SE is used to obtain real time data through state estimator and capture the real time data and compute loss sensitivities. RTCA/CSF is used to compute generator shift factors (or sensitivities) for the violated constraints both in base case and outage situations. The network data, loss sensitivities and the shift factors are passed to LMP system for dispatching the units and alleviating the constraints violations. The implementation of AOL and the test results for the constrained shift factor calculation are shown in the paper.

Based on our previous work (2005), this paper presents a SISO dynamic model for polymer electrolyte membrane fuel cells (PEMFCs) without using a reformer. Exact linearization approach is directly applied to the SISO dynamic model to obtain a nonlinear control strategy for PEMFCs. By adding an integral control term to the state feedback control law, the steady-state error due to parameter uncertainty is reduced. Simulation results show that PEM fuel cells have better transient and steady-state performances with the help of nonlinear control than linear controls.

This paper describes the basic concepts behind controller hardware-in-the-loop (CHIL) and power hardware-in- the-loop (PHIL) experimental testing from a renewable energy system integration perspective. An entire power apparatus or sub-system such as a power electronics converter for a fuel cell system or a variable speed wind power generator system can be tested in a controlled laboratory environment such as the 5 MW rated hardware-in-the-Loop (HIL) test facility established at the Center for Advanced Power Systems at Florida State University.

In 1980, the novel PLC system was used as a new system to communicate several computers in a building. Then, the PLC communication reliability and transfer rate up to 1600 bps was developed. PLC communication can work in environments with unpredictable parameters and long distances (Nunn, 1997). Nowadays, this communication channel is used in high speed transfer called broad power line (BPL). The main advantage of PLC is availability of its infrastructures in electrical network. In addition, by the extended form of this network, all consumers, even at long distance, can be accessed. Therefore, it is cost effective. Its optimum frequency range of this channel is 70-160 KHz. But, there are some problems. Noise is considered as the main constraint (Abraham, 1992). The main recourses of noise are as follows: a) 50 Hz harmonics that cause maximum disturbance in high speed data transferring and mostly attenuate and become narrow band at frequencies more than 30 kHz. B) The background noise that generated by household equipments, c) burst noise caused by industrial loads. Generally, noise of PLC channel is reduced in higher frequencies. Loss and attenuation are the other constraints as well as signal dispersion. Signal provides by actual channel limitation like bandwidth limitations and non-linearity leading to delay distortion of signal. Automatic meter reading (AMR) is one of the fields that can be performed by PLC communication channel. In this paper an AMR system besides of the above constraints is described.

This paper proposes a new method for transient stability analysis in terms of measuring critical clearing time using grid-computing technology. Grid computing is a highly developed system for jointly solving collaborative complex problems; those are required to solve in limited time and therefore they need high performance computing. Probabilistic transient stability analysis is one such application, which requires a lot of computation for accurate results. This paper presents the grid computing based approach for this purpose, which is able to measure the critical clearing time through time domain simulation by using this method. A prototype system is developed in our research lab in order to deploy this technique. Experiments are performed on the prototype grid for probabilistic transient stability analysis on New England 39 bus test system. Results show that this method has capability of providing accurate results with better performance.
