“…As a magnetic energy harvester, the magnetic core material can have a huge effect on the generating of induced voltage in the secondary coil terminals. 13 In previous works, 10,11 electrical steel was selected as the magnetic core material due its characteristic of high saturation flux density compared to other soft magnetic materials such as ferrite (0.3T) and nanocrystalline alloy (1.2T). To simulate a real environment, we use power line current supplied through a 380 V 3-phase distribution panel typically used in the industry, as shown in Fig.…”

“…The magnetic permeability of the saturated magnetic core is close to zero; this can cause power performance degradation due to such factors as insufficient induced voltage and power density. There have been several attempts to enhance the power density of magnetic energy harvesters, [9][10][11][12][13][14][15][16][17][18] but most of these attempts have not taken into account the effect of permeability variation, which is dependent on the geometrical parameters of the magnetic core and the magnetic field intensity. Assuming that permeability has a constant value at all locations of the magnetic core, regardless of the distance from the center of the power line, aspects of power performance like induced voltage of the magnetic core will be highly inaccurate.…”

Recently, magnetic energy harvesting technologies have been studied actively for self-sustainable operation of applications around power line. However, magnetic energy harvesting around power lines has the problem of magnetic saturation, which can cause power performance degradation of the harvester. In this paper, optimal design of a toroidal core for magnetic energy harvesters has been proposed with consideration of magnetic saturation near power lines. Using Permeability-H curve and Ampere’s circuital law, the optimum dimensional parameters needed to generate induced voltage were analyzed via calculation and simulation. To reflect a real environment, we consider the nonlinear characteristic of the magnetic core material and supply current through a 3-phase distribution panel used in the industry. The effectiveness of the proposed design methodology is verified by experiments in a power distribution panel and takes 60.9 V from power line current of 60 A at 60 Hz.

In smart grid applications, Wireless Sensor Networks (WSNs) which consist of battery limited sensor nodes are used on critical equipments of power distribution grids for monitoring purposes. WSN nodes have tight energy constraints hence it is important to reduce the energy consumption of sensor nodes due to harsh propagation characteristics of smart grid environment. One possible way to reduce the energy consumption is to utilize transmission power control where transmission powers are adjusted according to channel conditions. Another technique is to employ energy harvesting schemes to provide additional power for nodes by using environmental energy sources. Solar and electromagnetic energies are two possible environmental energy sources in outdoor substation environments. Solar energy can be efficiently exploited in a sunny day. On the other hand, electromagnetic energy can be used at any time. In this work, we propose a hybrid energy harvesting model that exploits both solar and electromagnetic energies and develop a Mixed Integer Programming (MIP) method to minimize the energy dissipation of sensor nodes. By using the MIP framework, we quantify the impact of the proposed hybrid energy harvesting model as well as transmission power control on the energy saving of nodes. Index Terms-smart grids, wireless sensor networks, energy harvesting, energy efficiency, mixed integer programming.
