“…The growth of these installations is due to their environmental advantages in addition to their social and economic benefits. Indeed, since building electricity consumption accounts for a large proportion of a country's overall consumption, and tends to increase further for the coming years, local generation offers an ideal solution [1][2][3][4].…”

In this chapter, a photovoltaic system integrated into the building is investigated. The studied structure includes also a battery energy storage system. The overall system is connected to a four-wire AC bus, with the possibility to supply single-phase and three-phase loads. Each equipment is interfaced with a dedicated power converter. This chapter examines the technical operation of all structure components and gives a detailed mathematical study of the DC/AC power converter control in case of two modes, namely, grid connected mode and standalone mode. The investigated control is based on resonant controller. The resonant controller parameters tuning, which is based on the generalized stability margin criterion, is detailed in this chapter. To prove the performance of the proposed control algorithm, several simulation tests developed under PSIM software were performed and then validated by experimental results.

“…In the literature, many electromagnetic disturbances are described, but one of the most dangerous for electrical and electronic devices is voltage surge. This disturbance has impulsive character and is mainly caused by atmospheric discharges (high energetic), both direct and indirect, or switching transient in the power grid [6].…”

“…In view of the considerable difficulties in the performance of tests at the place of installation of these kinds of device, their isolation from the impact of external electromagnetic fields and the risk of damage to or even destruction of the devices along with the difficulties, which are encountered (due to the complexity of calculations) during attempts at the analytical description of the phenomena related to the electromagnetic compatibility, the use of computer simulation tools is becoming more and more frequent. In the literature, a simulation approach is encountered using, for example, MATLAB and Simulink software to analyze the impact of lightning induced effects on small-scale, rooftop, and grid-connected PV systems [6], and observing the current and transient voltage that appear in the photovoltaic system after a lightning strike [8,9]. The main components of a photovoltaic installation are, among others, photovoltaic modules and inverters that convert the DC voltage generated from the module into AC voltage for connection to the power grid.…”

This paper presents a computer simulation model (in the MATLAB/Simulink environment) of a photovoltaic system disturbed by a 1.2/50 µs voltage surge pulse, while operating as part of the fixed system of an intelligent building. The tested part of the system consisted of a single PV module and a single-phase DC/AC voltage source converter provided with a maximum power point tracking system. The simulation of the test performed in accordance with the IEC 61000-4-5 standard required the development of a model of a surge waveform generator and a model of a coupling/decoupling network. The 1.2/50 μs voltage surge pulse was introduced into the system from the power grid side. During the test significant changes in the value of the AC voltage and current were found in the DC/AC converter system. The results of the computer simulation tests were verified with measurements performed in an accredited electromagnetic compatibility laboratory using the instructions specified in IEC 61000-4-5. The MATLAB/Simulink environment was proved as a useful tool of the assessment of effects of conducted electromagnetic disturbances on electronic/electric devices.

“…These problems affect changes in electric quality. The installation of a protective device behind the meter remains limited to a Surge Protective Device (SPD) [4][5][6][7][8] or a Transient Voltage Surge Suppressor (TVSS) [9], which contains Metal-Oxide Varistor (MOV) for transient overvoltage only. When installing SPDs on AC Surge, the power electronic devices of the inverter will be damaged, as seen in Figure 2.…”

This article presented multi-level swell voltage control for minimising the damage to an on-grid system between 1.3 to 1.8 pu. in compliance with the value regulated by IEEE and IEC standards. A window comparator circuit and comparator circuit with hysteresis transistor were used as the voltage detector and excessive pulse entering the multi-level control of the load. According to the designed function at every stage in the form of fail-safe AND gate, the system was set for this case by turning to the fail-safe mode in order to prevent a fail-dangerous mode that might harm the electric system if the device in the detection circuit is deprived of a qualification that is against the condition. Due to the Failure Mode and Effect Analysis (FMEA) in accordance with IEC-6196-1, the function prevents electric and electronic devices in the on-grid system from incurring damage. The design and installation of the electric protection device SVSS have a parallel-connect with the electric system without concern for the load current.
