In this article, a secondary voltage controller is proposed for ac microgrids, which ensures proportional reactive power-sharing among the distributed energy resources while their voltages stay within limits. the control objectives are formulated and analyzed as the steady-state control objectives, achieved by a nonlinear secondary controller for the energy resources. Both centralized and distributed forms of the proposed controller are presented, and the closed-loop system equilibrium and stability are discussed briefly. We show that the steady-state control objective is always achieved, if it is feasible. the effectiveness of the controller for different case studies is validated by adapting it to a microgrid system, based on the Conseil international des Grands Reseaux Electriques (CIGRE) benchmark MV distribution network.
Inertial sensor attitude estimation is essential for many applications, ranging from self-driving cars to tracking human movement. Ambient conditions, the presence of disturbances, and motion characteristics vary thro...

Proprietary systems and isolated solutions still dominate the Internet of things, making interoperability and flexibility between IoT platforms difficult. the W3C Web of things is emerging as a solution to improve the integration of IoT devices and services across multiple IoT platforms and application domains by leveraging and extending existing, standardized web technologies. To semantically describe things, WoT has defined the thing Description specification. thing Descriptions can be distributed in a wide variety of environments. In this paper a concept is presented to discover and retrieve thing Description network-independently. the collected thing Descriptions are then available via a web service. Due to different network structures, the effort faces some challenges which will be descripted in this work.

In recent years, the volumes of information processed and transmitted over the network are rapidly increasing, while the demand for speed and quality of transmitted data is also increasing. As a result, there is a need to use edge computing, which allows reducing network response time and more efficiently using bandwidth, as well as significantly improving the performance of the data transmission system. Article describes the application of edge computing in the form of transferring processes to an edge computing cluster, and presents the results of research on existing migration processes, full transfer time and downtime, identifying the optimal migration process for further implementation of the service migration automation algorithm. the following empirical research methods were used in the work: comparative evaluation method and experiment. the work considers the transfer of computational processes to an edge computing cluster;a comparative analysis of methods for automated service migration is carried out;an optimal migration strategy is identified;an algorithm for automating service migration is developed. Solutions related to automation of migration are excellent for use in the field of Internet of things. they contribute to improving application performance and reducing response time. Automatic service migration allows increasing process efficiency and reducing system maintenance costs."
