This paper presents an approach to coordinate Distributed Generation (DG) such that quantities in an unbalanced distribution system are balanced and power factor corrected. Models for the DG and three-phase distribution network are combined to form a set of Differential Algebraic Equations (DAE) that represent the behavior of the distribution system. Two state-feedback controllers with reference inputs...
This paper addresses parameter estimation for hybrid dynamical systems, such as electric power systems, with state-dependent events and time-delayed parametric switching. Previous work dealing with hybrid dynamical systems has addressed the calculation of trajectory sensitivities used in gradient-based parameter estimation methods, as well as the computation of proper sensitivity jump conditions at...
Online monitoring and diagnostics are important functions in the operation and maintenance of electric power systems. In this preliminary paper we present two new methods for electric power grid state and parameter estimation when a limited amount of grid information is available. The methods are based on developing a constrained optimization problem whose solution provides a set of desired grid information...
This paper presents an approach based upon state feedback to coordinate distributed energy resources (DER) across unbalanced phases of a power distribution system. The objective is to control the resources such that characteristics are balanced among phases making a more desirable load from the perspective of the transmission system. Example results are provided for a distribution system with inverter-connected...
This paper presents three heuristic algorithms that specify paths for a team of randomly placed robots to search a predefined area. The approaches are: a random movement with limited pre-path planning, a territorial claim with complete pre-path planning, and an expiring territorial claim with limited pre-path planning. The algorithms were simulated using Matlab and evaluated on the following criteria:...
Engineering design courses' content and timing have been the subject of debate for a long time. What is the appropriate content of an engineering design course and when is the appropriate time to introduce it in the curriculum? In this paper we present a look at a one semester junior level design course offered at New Mexico Tech, in which we propose a framework for introducing design in an engineering...
This paper presents a robust, easily upgradeable robotic platform for research along with its accompanying low-bandwidth and long-distance communication system. The proposed solution is a man-portable platform with easily accessible electronics bays and a communication system that uses free software, the Internet, and a cellular network. The design is made with the goal of developing multiple robotic...
Attempting to convey concepts and ideas in the subject area of robotic manipulators from within the confines of a static two-dimensional printed page can prove quite challenging to even the most gifted of authors. The inherently dynamic and multi-dimensional nature of the subject matter seems better suited to a medium of conveyance wherein a student is allowed to interactively explore topics in this...
