A microgrid based on direct current (DC) was designed and simulated for a small island in Belize. The energy generated in the microgrid will come from DC sources and the loads on the island will also be DC. Therefore, it was proposed to design a microgrid based on DC to reduce the amount of conversion losses between AC-DC.

For example, the aug-mented state approach turns joint estimation of an uncertain linear system with afne parameter dependencies into a bilinear state estimation problem. Following this path, it is typically difcult to provide convergence results [6]. Joint parameter and state estimation schemes that do provide

Dynamic state estimation is to predict the state vector one time step ahead and has the potential to foresee potential contingencies and security risks [9], [10]. Unlike the traditional state estimation and dynamic state estimation that focus on estimating relatively stationary state vectors, in this ARX dynamic response estimation, we

The difficulty of multi-person pose estimation is greater than that of single. In addition, based on the different tasks, it can be divided into two directions: 2D and 3D. 2D pose estimation

simultaneous state estimation and time-varying parameter estimation of a continuous-time nonlinear system. Using a set-based adaptive estimation, the estimates for the parameters and the state variables are updated to guarantee convergence. The algo-rithm is proposed to detect a fault in the system triggered by a drastic change in the

rameters. The parameter estimation algorithm entails a state estimation procedure that is carried out by non-Gaussian filters. The probability density function of the system state is nearly Gaussian even for strongly nonlinear models when the measure-ments are dense. The Extended Kalman filter can then be used for state estimation.
