“…For the design of the AC-DC converter controller, the hysteresis band control technique is used. This technique has been widely used in the literature for current control [22]. Its main characteristic is that the generation of the reference signal and its modulation are carried out simultaneously.…”

Microgrids have been widely adopted in many countries because they provide more reliable electricity service to those users connected to the power grid. These systems comprise various power sources, energy storage devices, and loads. However, detailed studies require considering linear and nonlinear loads, which are now used in this type of network. In addition, experimental tests require devices that emulate loads, represent different topologies, and construct assemblies for better identification, validation, and theoretical approximations of the power grid. Therefore, this paper presents a programmable electronic load to emulate linear and nonlinear loads of a microgrid, based on the control of a single-phase voltage source converter that considers rectification and power dissipation stages. Furthermore, a control stage allows power consumption variations, controlling the current demanded by the load, according to the reference current waveform programmed through a user interface. A synchronous reference frame phase-locked loop is implemented on a microcontroller. Thus, the programmable electronic load enables studying power quality in microgrids. Finally, the operation of the programmable electronic load is validated through experimental and simulation tests, considering different case studies.

“…The need for PFC in CFLs and LEDs to compensate for lagging power factor of below 0.64 and total harmonic distortion of over 136% in lighting applications is presented by Revelo-Fuelagán [31]. This is achieved by adding a PFC controller to the CFL electronic ballast and the circuit of the LED with a hysteretic control.…”

The introduction of electronic ballast in lighting systems design has dramatically revolutionized the lighting space. This is orchestrated by the entrance of the Compact Fluorescent Lamps (CFLs) and Light Emitting Diodes (LEDs) into the lighting market. The CFLs currently being used in domestic and industrial lighting systems provide highly competitive alternatives to conventional incandescent lamps. The electronic ballast incorporated into the CFLs helps eliminate the flickering and slow starting flaws prevalent in traditional fluorescent lamps. To properly evaluate the performance characteristics and limitations of the CFLs, a critical analysis of its electronic circuit becomes imperative. To this end, this paper presents experimental and simulation analyses of the CFL circuits. To achieve this, two Futina CFL bulbs of 11W and 15W model YPZ220/11-BMSP RR/RDD and YPZ220/15-BMSP RR/RDD, respectively, were analyzed and experimentally verified. A function-based programming paradigm was applied to develop a graphical user interface (GUI) used for the circuits analyses. The GUI is designed using MATLAB graphical user interface development environment (GUIDE). Experiments were conducted to obtain the performance characteristics of the CFLs, and measurements show that the 11W lamp has a higher amplitude than the 15W lamp. However, both lamps show similar waveforms after 300 seconds. The maximum voltage amplitudes for both CFLs are the same, with a peak value of 218V. The current waveforms in the spectral domain gave a maximum amplitude of 0.3 A for the 11W CFL and 0.2 A for the 15W. The voltage frequency (0.00196) of both CFLs are the same, whereas the current frequencies are different. This indicates that the wattage of a CFL does not affect the frequency of its voltage waveform. The frequency of the 11W CFL current (0.00157) is higher than that of the 15W CFL current (0.00784). This implies that the higher the CFL wattage, the lower the frequency of its current waveform. Additionally, simulation results revealed that the key difference between the CFLs is the current total harmonic distortion (THDI), which increases with an increasing rated power of the CFL or the aggregation of a number of the smaller rated CFLs.

Rapid development in electrical technology has imposed strong challenges to modern power system. Power quality has become a great concern due to proliferation of power electronic technology in modern electrical loads. Specifically for lighting load such as compact fluorescent lamps (CFLs), one of the concerning issues is harmonics. CFL is a cost-competitive and energy efficient compared to incandescent lamp. Inevitably, CFL produces harmonics current due to nonlinearity behaviour of the electronic ballast circuit. This paper presents a study on the widespread installation of CFL lamps in electrical power network. Initially, the harmonic current characteristics of local-branded CFL was identified from laboratory measurement. Then, a simulated CFL model was developed in MATLAB/Simulink to replicate the identified characteristics. The same step was repeated for other two different brands where eventually all models were embedded into a distribution network. The results show that at low voltage level, with installation more than 50 units for each type of CFL, the harmonic voltage distortion exceeded the 8% total harmonic distortion (THD) limit as stipulated in EN50160 standard. However, at higher voltage, the amount of THD decreased to average 0.94% and further down to average 0.28% at small transmission voltage level.
