There continues to be many advances in the theory and practice of Modeling and Simulation (M&S). However, some of these can be considered as Grand Challenges;issues whose solutions require significant focused effort across a community, sometimes with ground-breaking collaborations with new disciplines. In 2002, the first M&S Grand Challenges Workshop was held in Dagstuhl, Germany, in an attempt to focus efforts on key areas. In 2012, a new initiative was launched to continue these Grand Challenge efforts. Panel members of this third Grand Challenge present their views on M&S Grand Challenges. Themes presented in this panel include M&S Methodology;Agent-based M M&S in systems engineering;Cyber systems Modeling;and Network Simulation. © 2013 ACM.

The introduction of the smart grid concept and advanced metering infrastructure (AMI) technologies in the power systems area has attracted new attention to make distribution systems efficient and save more energy. Volt/VAr control is a commonly performed technique which enables utilities to run distribution systems on lower voltage resulting in higher energy savings. Although this technique has been implemented in distribution systems for a long time, new research is needed to adapt volt/VAr control with contemporary technologies' additional information and feedback. Voltage regulators and capacitor banks are used as two main control devices in the volt/VAr control scheme. With smart grid development, feedback from end-of-line (EOL) in distribution systems is provided. Furthermore, utilities installed more switch capacitors instead of fixed capacitor banks. In this paper, a volt/VAr control scheme is proposed to take aforementioned evolutions into account. The volt/VAr control problem is developed as an optimization problem in which the particle swarm optimization (PSO) technique is used to find an optimum solution for voltage regulator tap settings and switch capacitors status. The developed PSO algorithm is validated against an enumerative search strategy to ensure its correct execution. The proposed algorithms are implemented on the IEEE 13 bus distribution test system.

One of the most important goals of smart grid is sustainability. Load management in coordinated manner may help in saving more energy and hence move towards sustainability. Advanced metering infrastructures (AMI) and bidirectional communication between electricity grid and end-users, novel technologies and designs are required to exploit full potential of smart grid investments. New analysis tools and control strategies are needed for distribution systems to augment these investments. Heating, ventilation and air conditioning (HVAC) systems, as thermostatic controllable loads, consume major portion of electric energy. In this work, a detailed load model of thermostatic electric loads is used to develop a novel approach of look-ahead controller over different time frames. Developed controller has been tested for cooling mode operation on a typical summer day and shows satisfactory performance.

Orientation estimation is very important for development of unmanned aerial systems (UASs), and is performed by combining data from several sources and sensors. Kalman filters are widely used for this task, however they typically assume linearity and Gaussian noise statistics. While these assumptions work well for high-quality, high-cost sensors, it does not work as well for low-cost, low-quality sensors. For low-cost sensors, complementary filters can be used since no assumptions are made with regards to linearity and noise statistics. In this paper, the concepts of filtering based on fractional-order calculus are applied to the complementary filter, and the efficacy of non-integer-order filtering on systems with non-gaussian noise is explored with good success.

A fuzzy c-regression model clustering algorithm based on Bias-Eliminated Least Squares method (BELS) is presented. This method is designed to develop an identification procedure for noisy nonlinear systems. The BELS method is used to identify consequent parameters and eliminate the bias. The proposed approach has been applied to benchmark modeling problem which proved a good performance.

This paper reports on a new hybrid TD-AIM-MOD scheme for analyzing transient scattering from the perfect electrically conducting structures. The scheme reduces the computational complexity of a classically formulated MOD solver from N o 2 N s 2 to N o log 2 N o N s 1.5 log 2 N s - here N o is the maximum order of the Laguerre polynomials used to expand the temporal current signature. Just as in MOT-TD-AIM solvers, the scatterer is embedded in a 3D regular grid and sources are projected onto this grid via moment matching. Next, fields are propagated on this grid by using a 3D spatial FFT and a blocked 1D “temporal” (order) FFT. Finally, fields at observers are obtained by interpolating their values from the regular spatial grid, followed by a near field correction operation. The accuracy and stability characteristics of the TD-AIM-MOD method are demonstrated via its application to large-scale scattering problems.

In this paper, efficiency analysis and design of contactless electric energy transmission systems using inductive method are elaborated. Large leakage inductances of the systems are to be compensated to achieve resonance conditions for maximum efficiency in energy transfer from a launch side to a receiving side where compensating circuits are utilized in both sides. Considering the circuit models of a contactless electrical energy transmission system, the effects of different system parameters including the compensating capacitors are analyzed for a specified frequency range and coupling factor. An algorithm is proposed to determine the optimal compensating capacitors and system resonance frequency to achieve high efficiency. © 2012 IEEE.

Conducting a systematic literature review (SLR) is difficult and time-consuming for an experienced researcher, and even more so for a novice graduate student. With a better understanding of the most common difficulties in the SLR process, mentors will be better prepared to guide novices through the process. This understanding will help researchers have more realistic expectations of the SLR process and will help mentors guide novices through its planning, execution, and documentation phases. Consequently, the objectives of this work are to identify the most difficult and time-consuming phases of the SLR process. Using data from two sources - 52 responses to an online survey sent to all authors of SLRs published in software engineering venues and qualitative experience reports from 8 PhD students who conducted SLRs as part of a course - we identified specific difficulties related to each phase of the SLR process. Our findings highlight the importance of planning, teamwork, and mentoring by an experienced researcher throughout the process. The paper also identifies implications for the teaching of the SLR process.
