Residential housing is increasingly oriented toward all-electric consumption, also replacing gas loads. Users are under contract by an electricity provider that sets a power threshold above which the supplied is interrupted, that means it is increasingly difficult to stay below the threshold. The paper proposes an innovative device, called PowerAlert, that could show real-time power consumption with an audible signal related to the power thresholds set by the user. It is possible to switch the display between power consumption and the real-time clock with a simple push button. During device configuration is possible to connect it to a wireless network, to set a power meter among those available and its IP address. It is also possible to set three power thresholds referred to three different frequencies of the buzzer as alarm. This device can also be useful for monitoring modern electric devices that work in pulse mode and thermally stress protections that might intervene later. This paper is an extended version of a paper presented in I&CPS Las Vegas 2024 [1]

IEEE Transactions on Industry Applications

The change in the electrical nature of the loads together with the loss of linearity are increasingly common phenomena in buildings, which requires special attention during the design phase of the electrical system in order to avoid problems in the management of reactive power flows and to better manage the power quality of the system. The presence of distributed nonlinear loads determines unusual behavior in terms of reactive power flux for the high harmonic distortion and for the capacitive behavior of the loads. Capacitive behavior is often evident when measuring reactive power in electrical systems feeding tertiary or commercial buildings, they feed reactive power at certain times of the day from a private network into a public network. The aim of this work is to analyze the performance of power systems feeding non-linear distributed loads with harmonic distortion and capacitive behavior, highlighting when this is real and when it is simply due to incorrect power factor measurements. If the behavior is truly capacitive, the problem can be solved by replacing the power factor correction systems with static compensators that are able to compensate reactive power for both capacitive and inductive behavior, working on all 4 quadrants. At the end, a real case study shows the unusual behavior of the distributed non-linear loads.

Commercial Battery Energy Storage Systems are equipped with a standard control unit with simplified logic, able to reduce the impact of the power system on the electric grid. The standard control is locked in a closed environment without any chance to modify the logic. The control unit receives signals from current sensors located at the entrance point of the power system. This paper presents a proposal of innovative device called Smart Digital Current Simulator as a substitute of those current sensors, aiming to generate a sinusoidal signal that falsifies the real induced current inside current sensor's windings by house power leads, in order to fool the control unit to inject or withdraw the desired electric power from or to the electric system. This paper shows a prototype of the suggested device completed of the open sources Node-Red server, Mosquitto broker and Home Assistant Container. This device communicates through Mosquitto protocol and can be managed by a user-friendly Graphic User Interface with open logics to manage a user-desired charge and discharge. Also, allows complying Demand Side Management and Demand Response strategies, otherwise not possible. Moreover, it is useful to buy energy when the price of electricity is below a specific threshold or the Battery Storage power is preferred instead of the grid power when the price of electricity is above a specific threshold. Finally, is able to perform a peak shaving to keep the withdrawal of power constant from the grid. This paper was presented in the conference IEEE IAS Nashville 2023 [1].

In the present paper an innovative street lighting system with solar PV and battery as the source of electricity was monitored and analyzed considering a case study installed in Italy center. A Light Emitting Diode (LED) is used together with a dimmer control system. This application is new because high efficiency PV cells are applied to the cylindrical surface of the pole: monocrystalline cells have diodes able to bypass the cells that are not directly irradiated by sun to allow the best performance of the PV. The data of this solution were monitored for one year in terms of LED consumptions, current, voltage, PV power, and charging-discharging performance of the battery. These electricity parameters were hourly investigated considering different boundary conditions (weather parameters). These results allow to propose different optimization strategies in terms of scheduling and management of the system related to all the electrical components. The best sizing of the PV and the optimal scheduling profile were proposed based on the experimental and numerical analysis.

This study examines the electrical performance and management of hybrid solar street lighting systems with the objective of optimizing their operation for sustainable urban development. Hybrid solar streetlights, which integrate photovoltaic panels with additional power sources, offer resilience and reliability that are crucial for urban settings. A hybrid solar streetlamp was installed in a city in central Italy and monitored for over a year to analyze its electrical behavior and the illuminances obtainable under different boundary conditions and operational programs. The measured data permit the development of an optimization algorithm in a Python program for the optimal management of the solar streetlamp and the forecasting of the battery charging/discharging cycles, as well as the electricity taken from the grid. The simulation scenarios permit the development of a novel management algorithm that is capable of optimizing the battery usage with a minimal draw on the grid in order to achieve a state of near self-sufficiency for the solar streetlamp. The results demonstrate that tilted solar panels enhance energy production, while optimized LED power profiles and system management enhance efficiency. The study highlights the importance of maintaining the state of charge (SOC) of the battery above 20% to extend its lifetime and reduce replacement needs. Economic analysis indicates significant potential energy savings, emphasizing the necessity of system optimization for economic viability and environmental sustainability in urban lighting. Despite initial investment costs and challenges, adopting hybrid solar lighting in urban environments presents substantial benefits, paving the way for a more sustainable and energy-efficient urban future.
