With the advent of the Fourth Industrial Revolution, Internet of Things (IoT) and robotic systems are closely cooperating, reshaping their relations and managing to develop new-generation devices. Such disruptive technology corresponds to the backbone of the so-called Industry 4.0. The integration of robotic agents and IoT leads to the concept of the Internet of Robotic Things, in which innovation in digital systems is drawing new possibilities in both industrial and research fields, covering several domains such as manufacturing, agriculture, health, surveillance, and education, to name but a few. In this manuscript, the state-of-the-art of IoRT applications is outlined, aiming to mark their impact on several research fields, and focusing on the main open challenges of the integration of robotic technologies into smart spaces. IoRT technologies and applications are also discussed to underline their influence in everyday life, inducing the need for more research into remote and automated applications.

“…A centralised dispatch structure with 15–60 min control time scale is widely adopted in the MV level [4, 25, 26] while second‐core‐planning for three‐phase distribution networks have been validated [27]. Meanwhile, distributed control structures are more and more used in the LV level considering the LV level's limited computation and communication ability [24] while the consensus algorithm can achieve quick response to disturbance in the second control stage [14] with a simple localised calculation [16, 17]. All the designs about the control structure and control model are based on the widely used structure and control time scale.…”

“…However, PV inverters are not easily coordinated by local strategies. To fill this gap, PV inverter‐based distributed RPC strategies [13–15] and energy storage system (ESS)‐based active power control (APC) strategies [16, 17] have been proposed to achieve coordination with limited configurations for communication and computation. Furthermore, distributed control strategies simultaneously coordinating APC and RPC were proposed in [18, 19].…”

This paper presents a hierarchical coordination method to improve operation conditions between the medium‐voltage distribution network (MVDN) and low‐voltage distribution networks (LVDN) considering high‐level residential PV units integrating LV distribution networks. It addresses the following issues: (i) rapid power fluctuations and unbalance caused by high‐level residential PV units passes to the MV distribution network via the point of common coupling (PCC) and thus increase operation challenges; (ii) power fluctuations, voltage violations and unbalance simultaneously happens in the LVDNs. A hierarchical coordination structure the MVDN and LVDN is proposed. In the MV level, a centralized dispatch method based on three‐phase optimal power flow is developed in the timescale of minutes to minimize the power losses, unbalance and PCC adjustments, which are achieved by regulating energy storage systems (ESSs) and PV inverters in the LV level. In the LV level, a distributed control model based on a consensus algorithm is proposed in the timescale of seconds to track the reference active (or reactive) power at the PCC given by the MV level and mitigate its fluctuations. Simulations studies are performed to verify the proposed method.

This paper presents an overview of the impact of high penetration of photovoltaic (PV) systems in low-voltage distribution networks (LVDNs). High integration of solar PVs in the LVDNs has severe implications on the system parameters, efficiency, and stability. This paper also introduces the methods that have been driven to overcome these effects to preserve the steady-state conditions in the system during excessive penetration of PV generation units. A comparison between the contributions and shortcomings of the most recent researches for overvoltage mitigation strategies has been driven. Also, it includes comparing different overvoltage mitigation methods to handle the impact of the overvoltage under high penetration of PV units in the LVDNs. Besides, it presents a comparison between overvoltage mitigation methods based on their pros and cons.
