In this article we consider the problem of managing the power flow among different components of a microgrid while ensuring that the demands of all loads are satisfied. In order to address this problem, we propose a distributed scheme where only one sensor (for each subgrid in the microgrid) broadcasts a single scalar variable though a wireless communication network (e.g., WiFi, ZigBee, cellular communication network). More precisely, in the proposed scheme each generation/storage subsystem is able to adjust its operating set‐point only making use of the feedback from the sensors. This architecture provides the system with plug&play capabilities. Interestingly enough, the proposed scheme provides the optimal power flow for the whole microgrid without any information on the demanded load. In this article we apply the proposed approach to hybrid ac/dc microgrids; however, the scheme is general and can be applied to any type of microgrid. The effectiveness of the proposed scheme is evaluated through extensive simulations and compared with a centralized optimal strategy.

“…Regarding the model exploitation, there is a work ( [1]) that algorithmically addresses Power Maximization Problem and make use of the vector model for WPT networks. Generally, the main problem to solve concerning EMR, is to maximize the received power while the radiation level remains low ( [3], [4], [13]) and vice versa, in the sense that we try to minimize radiation levels and sufficiently charge the devices ( [12]). In [3], the authors consider the Safe Charging with Adjustable PowEr (SCAPE) problem, where they adjust the power of chargers to maximize the charging utility of devices, while assuring that EMR intensity at any location in the field does not exceed a given threshold.…”

Wireless power transfer (WPT) is an emerging technology that is used in ad hoc networks of battery-powered devices, to deliver energy and keep the network functional. Existing state-of-the-art studies have mainly focused on applying this technology, but the potential risk of electromagnetic radiation (EMR) exposure is really overlooked by them. This still holds for the general case of the RF Wireless Communication networks. Hence, we consider The Minimum Radiation Path Problem of finding the lowest radiation trajectory of an agent moving from a source to a destination point in a network plane.Different from previous works, we attempt to study (for the first time in the state-of-the-art) path radiation under a more realistic WPT model than the usual one-dimensional models, that have been used in the past and cannot capture interesting superadditive and cancellation effects between distinct electromagnetic sources. In the light of the above, we design and evaluate both an algorithm and a heuristic that achieve different trade-offs between radiation and trajectory length of a moving agent.

“…In this paper, we propose two adaptive beam-steering algorithms to address the RF-EMF radiation exposure problem that may arise in the WPT system. To the best of our knowledge, this work is one of a few papers proposing the solution for this safety issue [20]- [22]. The algorithm for a distributed wireless charging system was studied by [20], where the authors use a feedback-based dual ascent method to optimize the transmitted power while satisfying the RF-EMF exposure limit.…”

The algorithm for a distributed wireless charging system was studied by [20], where the authors use a feedback-based dual ascent method to optimize the transmitted power while satisfying the RF-EMF exposure limit. Instead of using an RF propagation model to estimate the RF-EMF exposure at a specific location, like in their prior work [21], here they use the simulated measurements as feedback to emulate the real-life situation.…”
