Grid-connected photovoltaic power systems always have a connection to a utility grid via a suitable inverter because a PV array only produces a DC power. This paper presents fault diagnosis and troubleshooting on 2.1 kW grid-connected photovoltaic power system in UiTM Pulau Pinang as a case study network. Grid-connected PV systems has a solar panel...

This paper proposes the modern approach using Particle Swarm Optimization (PSO) algorithm in determining the ideal value of Proportional Integral (PI) gain for current controller of Permanent Magnet Synchronous Motor (PMSM). Controlling the torque of PMSM and optimizing the PI-gain are the main objectives of this project. The PI controller is emplo...

p class="Abstract">Power-Voltage (P-V) curve and Current-Voltage (I-V) curve determine the performance of the PV system. In this work, the arrangements of the PV module were reconstructed by adding the number of PV module in 3 strings configuration from 5 to 45. This method enhance the performance of the PV system as it able to show the characteris...
Conference Paper
This research focuses on increasing output voltage of the photovoltaic (PV) system while implementing maximum power point tracking (MPPT) technique. In order to increase the output voltage of the system, boost converter is connected to the PV system. However, when connecting boost converter to the PV system the voltage value at the output equal to...

— This paper proposes modification of an adaptation scheme which aims to replace the conventional PI controller for MRAS by using Fuzzy Logic Control (FLC). This FLC based on Takagi-Sugeno Fuzzy Logic Inference System (FIS). To achieve this goal, field oriented control (FOC) method has been utilized to control the speed of PMSM with the implementat...

—Network reconfiguration is a process of changing the original structure of the distribution network system with the intention of balancing the load in every system’s feeder at the same time to optimize the operation of the system. The process involve the changing of switching state (tie switches and sectionalize switches), with the aim to find the...

Conventional Maximum Power Point Tracking (MPPT) controllers are widely used due to simple implementation and show a good performance in tracking Maximum Power Point (MPP) when solar irradiance is uniform. However, when partial shading occurs on the PV array, tracking to MPP becomes complicated as multiple peaks exist on the Power-Voltage (P-V) cha...

A conventional electrical distribution system are not designs to deal with harmonics because at that time the linear load conquer the consumer demand. Over the years with growing use of nonlinear load such as personal computer can contribute to harmonics current occur on electrical distribution system. With the presence of harmonics current on elec...

Model reference adaptive system (MRAS) is one of the popular methods to observe the speed and the angle information of the Permanent magnet synchronous motor (PMSM). This paper proposes a new adaptation scheme for MRAS to replace the conventional PI controller based on Popov Hyperstability theorem. In this project, the speed of PMSM is controlled b...
Conference Paper
This paper presents the implementation of the permanent magnet synchronous motor (PMSM) controller by using Field Oriented Control (FOC) method. The digital signal processor (DSP) was used as a controller to interface between the FOC and the PMSM. In this project, a fixed 32 bit DSP controller TMS320F2808 is used to realize the drive system.

... These functions are commonly used in control applications, using a set of fuzzy logic rules, a reference and measurement are supplied in and some actuating signal is produced. There are basically two approaches to FLC [10]. Mamdani and Takagi and Sugeno's approach. ...
... The advanced techniques of boosting or enhancing power generation in photovoltaic arrays employ fuzzy logic or artificial intelligence and sophisticated algorithm like particle swarm optimization (Burhanudin et al., 2017;Humada et al., 2014a;Karatepe et al., 2007), perturb and observe (Bianconi, Calvente, & Giral, 2013;Rezk & Eltamaly, 2015) and slide mode control (Vázquez, Azaf, Cervantes, Vázquez, & Hernández, 2015) to distinguish local maximum from a global maximum during maximum point power tracking. The benefits accrued from these techniques have been widely published but the magnitude of power generated relative to the tied or linked method is not much compared to the resource input into these methods. ...
... Permanent Magnet Synchronous Motors (PMSM) are increasingly widely used in civil and industrial applications because of their high efficiency, high power density, low maintenance cost, and lower permanent magnet price. The vector control method's popularity, including Field Oriented Control (FOC) [1][2][3][4][5][6] and Direct Torque Control (DTC) [7][8][9][10], stems from its advantages of simplicity in the control structure, ease of operation, reliability, and high efficiency [11,12]. ...
... In addition the damage of PV panels should not be ignored because of change in output power of PV array that causes serious reduction in the efficiency of the system [2]. In literature [1][2][3][4][5] PSO application is described for multipeak curve which is fast and adequate. In literature [8] the traditional methods for tracking maximum power are described i.e. ...
... This approach allows obtaining full flux-torque-current maps and recalculating current trajectories offline. It is also well suited for sensorless control of motor, since most of the accurate closed-loop observers, such as EFK-observer or MRAS-observers, as well as modelpredictive controllers, should contain a detailed model of the motor, and particularly for SynRM the values of inductances should be pre-identified accurately [15][16][17]. ...
... This two current also can be controlled independently. Then, the flux and torque current will be compared with the current flux and torque reference (i sdref and i sqref ) that were produce from the T-S FLC [6]. At this point, the current will be used to control the synchronous or HPVM machine by changing the flux and torque reference current. ...
... It produces high torque and low current at the starting of the motor. Fig. 1 illustrates the block diagram of the FOC of the PMSM machine [6]. The mathematical modelling of the PMSM machine is based on the dq synchronous reference frame give as follows Fig. 1, stator current measured and stator space vector is transformed  using Clarke's transformation., these variable are time-variant. ...
