“…Environment-dependent RE technology, such as solar and wind, is prone to the effects of voltage fluctuations. Therefore, when there is fluctuation present in the grid, overvoltage relay will trip off to protect the inverter [85]. However, for this reason, this would not be feasible as it would indirectly…”

“…As defined in IEEE 1159-1995 [83,84], voltage sags and swell are a type of power quality problem that occur when there is an increase or decrease of its root mean square within a half cycle to a minute. A short decrease in power supply or load current to less than 10% of the nominal voltage in less than one minute is often classified as an interruption [85]. Voltage sag often causes tripping issues, overheating of inductive equipment, flickering of light, and damage to sensitive electronic device.…”

Electric supply is listed as one of the basic amenities of sustainable development in Malaysia. Under this key contributing factor, the sustainable development goal aims to ensure universal access to an affordable, clean, and reliable energy service. To support the generation capacity in years to come, distributed generation is conceptualized through stages upon its implementation in the power system network. However, the rapid establishment growth of distributed generation technology in Malaysia will invoke power quality problems in the current power system network. In order to prevent this, the current government is committed to embark on the development of renewable technologies with the assurance of maintaining the quality of power delivered to consumers. Therefore, this research paper will focus on the review of the energy prospect of both fossil fuel and renewable energy generation in Malaysia and other countries, followed by power quality issues and compensation device under a high renewable penetration distribution network. The issues and challenges of distributed generation are presented, with a comprehensive discussion and insightful recommendation on future work of the distributed generation. In accordance with the addressed highlights in this paper, it would serve as the criterion on upcoming revolution of distributed generation integrated along with the traditional network in Malaysia.

“…The normal operation of the largely sensitive load in a distributed system is affected by the voltage quality problem, which results in several economic problems with attendant adverse effects [3]. The most frequently recurring disturbances in the distribution network are voltage sags and swells [5,6]. The processes of transformer energizing, motor starting and faults on the distribution line have been identified as causes of sags and swells.…”

The main purpose of this work is to introduced power quality improvement in low voltage distribution networks with the application of Improved Unified Power Quality Conditioner (I-UPQC). Ordinarily, in the normal UPQC, the series inverter handles active injection while the shunt inverter provides load imaginary power injection. However, in the case of I-UPQC, the series inverter of the UPQC performs two functions concurrently as a sag and swell compensator and assists the shunt inverter in load reactive power requirements. The reactive power sharing is achieved by the integration of the Power Angle Control (PAC) of UPQC to coordinate imaginary power-sharing between the two inverters. With the view that the series inverter produces active and reactive power, this concept is named I-UPQC. Full mathematical analysis to extend the PAC method to I-UPQC has been carried out in this work. The simulation and results produced in the MATLAB / SIMULINK environment and discussion to support the developed concept are also presented. The result from the proposed concept is confirmed by comparing the concept with operation unified power quality conditioner in steady-state.

“…The current worldwide economic competitiveness requires the organizations to be stricter in delivery times, following the just-in-time production model, and the profit margins tend to become smaller. Thus, any interference in production may lead to failure in delivery, sometimes implying large economic (direct and indirect) losses [1], [2] and [3]. The constant modernization of the manufacturing processes is based on the widespread use of electronic equipment.…”

Part 16: Operation Issues in Energy - IIInternational audiencePower quality issues have taken a more prominent role in power systems over the last years. These issues are of major concern for energy customers, primarily for customers with a widespread use of electronic devices in their manufacturing processes. Even though the quality of service is increasing, customers are becoming more demanding of the energy provider. This research aims to provide some industrial managers the technical support in deciding of investments in the mitigation of power quality disturbances, such as the use of less sensitive devices or the use of interface devices (UPS, DVR ...) In order to recommend an appropriate solution, the problem is characterized. The technical and economic influences of the PQ disturbances in the manufacturing processes are assessed resorting to power quality audits in the customer facilities. This research covered a significant number of facilities in several industrial activities
