“…Substituting Equations (5) and (6) into Equation 1, the accurate expression of mutual inductance between coaxial Archimedean spiral coils can be obtained by: 7in this paper is a double integral, so its integrand can not be represented by an elementary function. Thus, the composite integral method combined with Gaussian quadrature formula with four points [20] is adopted to solve the double integrals numerically in the whole paper.…”

“…Planar spiral coils have been widely used in high-frequency fields such as wireless power transmission [1,2], printed circuit board-based magnetic components, and on-chip coils [2,3]. In the design of the coils, mutual inductance is an important parameter [4,5]. Since Maxwell's study, mutual inductance calculation has been considered as a basic scientific problem for all coupling coils [6].…”

Considering the helicity of Archimedean spiral coils, this paper proposes accurate expressions of mutual inductance and their numerical calculation methods, which can be applied in the wireless power transmission field, etc. Accurate expressions of mutual inductance are deduced respectively for two coils that are coaxial, laterally misaligned, or non-parallel, and numerical calculations are performed using Gaussian integration as well. In the case of coaxial coils, the calculation results are verified by the 3D finite element method (3D FEM) and compared with the results gained by the traditional method that approximates two spiral coils to two clusters of series-connected circular coils ignoring helicity. The comparison of the three methods shows that results achieved by the proposed expression are close to that of 3D FEM, while there is increasing error with the screw pitches of the coils when using the traditional circular coil approximation method. The influence of relative position on the mutual inductance of the two coils is also studied and it is further explained through magnetic field distribution. Finally, the validity of the proposed expressions of mutual inductance is verified by experimental results.

“…The Internet of Things (IoT) can integrate objects to the Internet. To achieve that, the IoT infrastructure is composed by embedded smart devices, with limited computational resources, which are able to provide certain real time services, such as monitoring, communications, controlling, among others [5], [6]. This idea can be extended to IoE which deals to interconnect distributed energy resources by means of the Internet [7].…”

Microgrids are moving toward electric power systems in a sort of an internet of energy (IoE) where a large number of generators can be connected anywhere. In this regard, to realize the envisioned IoE, information and communication technologies (ICT) are crucial for developing innovative applications and services as well as achieving high levels of efficiency in microgrids. However, due to the variety of ICT, there is not a de facto standard solution to implement IoE platforms. Moreover, standards for the current Internet of Things (IoT) platforms are not optimal for developing IoE platforms, which present more demanding challenges. In such context, this paper presents an embedded IoE platform for management of smart microgrids. The performance of this platform has been tested in an experimental microgrid. Results show that the proposed platform fulfills the microgrids requirements and it is able to manage the energy flows, the safety issues, etc. in microgrids.
