In this paper, our main objective is to present a set of algorithms and software tools that analyze paths produced in laboratory and real-world settings, allowing measurement of the deviation between paths, as well as determining how points on one path correspond to points on a second path. Potential applications of a general-purpose path mapping technique

Computational research in this area has typically focused on trajectories (Yanagisawa et al., 2003 Chen et al., 2005) where timing is available, but in many cases the timing is either not known or is irrelevant, and so there remains a gap in algorithms and tools for analyzing paths and measuring path similarity and deviation based on their shapes alone. Nevertheless, both paths and trajectories have become important data sources in scientific research and machine intelligence applications, and their use is only bound to increase as research and applications take advantage of mobile GPS-enabled devices and other automated means of recording location. Importantly, two trajectories that mismatch in their timing might be judged as very different, even if their paths are nearly identical. In contrast to trajectories (which refer to paths as a function of time), a path typically ignores or lacks timing information, making it both more general and at times less informative.
#Grid mapping approach series#
Paths are multi-dimensional spatial data series that represent an ordered sequence of locations in space.
#Grid mapping approach code#
We also describe available software code written in the R statistical computing language that implements the algorithm to enable data analysis. We describe the algorithm and show its results on a number of sample problems and data sets, and demonstrate its effectiveness for assessing human memory for paths. Unlike similar algorithms that produce distance metrics between trajectories (i.e., paths that include timing information), this algorithm uses only the order of observed path segments to determine the mapping. The method is robust to a number of aspects in real path data, such as crossovers, self-intersections, differences in path segmentation, and partial or incomplete paths. ALCAMP measures the deviation between two paths and produces a mapping between corresponding points on the two paths. In this paper, we describe an optimization approach for robustly measuring the area-based deviation between two paths we call ALCAMP (Algorithm for finding the Least-Cost Areal Mapping between Paths).
#Grid mapping approach manual#
Previously, approaches for measuring the similarity or deviation between two paths have either required timing information or have used ad hoc or manual coding schemes. Case studies with simulations and experimental results have verified the effectiveness and flexibilities of the proposed power control strategy to release the advanced features.Many domains of empirical research produce or analyze spatial paths as a measure of behavior.

The MPPT control is deactivated, and the PV power has been reduced to the target value delivered by the inverter at the Point of Common Coupling.

Under grid voltage dips, the PQ-control strategy has been changed within the grid voltage sag levels and the inverter rating currents. Their aim is to maximize the PV power and to inject into the grid a current with low harmonic distortion, as well as energy at unity power factor. In normal operation mode, a Maximal Power Point Tracking (MPPT) algorithm and PQ-control loop have been designed around the converters. This control approach can be configured in the PV converters and flexibly change from one to another mode during operation. This paper proposes a flexible power control of a three-phase grid-connected PV system which fulfills the PV converter operations under normal conditions and symmetrical grid voltage sags.
