Distributed Generation: A Review on Current Energy Status, Grid-Interconnected PQ Issues, and Implementation Constraints of DG in Malaysia

Abstract

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.

Electric Power Network Interconnection: A Review on Current Status, Future Prospects and Research Direction

“…The second generation of power grids are specified by large-scale interconnection and development of the zoned and layered power grids. On this behalf, the power grids of third generation will form the power grid mode of local grids, organically combining backbone grids and microgrids [18,19].…”

Transient Fault Detection and Location in Power Distribution Network: A Review of Current Practices and Challenges in Malaysia

“…This is due to several internal behaviors such as partial shading, panel contamination, and degradation component. Therefore, an upgraded fault detection scheme based on several studies is proposed for future employment [218]. Figure 13 illustrates the modification of fault detection schemes based on parameters behavior from various studies that have been conducted such as data driven, process control, and knowledge based [219].…”

Analysis of Traditional and Alternative Methods for Solving Voltage Problems in Low Voltage Grids: An Estonian Case Study

“…A key characteristic of an electricity distribution system is its ability to ensure a reliable and quality power supply to connected loads and DGs. Several studies have investigated how the presence of DGs and power electronics based on non-linear loads influence power quality in low-voltage grids and how the negative effects can be mitigated [1][2][3][4][5][6][7]. The study reported in [8] states that the uncontrolled charging of PEVs has negative effects on network demand, voltage unbalance factor (VUF), and the voltage profile of the LV distribution grid, while [9] lists line congestion, voltage drops, inverse power flows, increased energy losses, and power quality (PQ) as problems related to DG and PEV charging stations.…”

“…Since the classical grid reinforcement approach to mitigate the described problems requires significant investments from the DSO, alternative measures have been investigated. The authors of [7] provided a characterisation of PQ compensation devices along with respective current control strategies, while also discussing alternatives for a series of flexible alternating current transmission system (FACTS) devices such as battery energy storage systems (BESS), solid-state transfer switches, transformer tap changers, maximum power point trackers (MPPT), and a grid feeding configuration. The study presented in [22] proposes a method to compensate for active power loss in one phase by the remaining phases, so that the total energy exchanged with the grid remains unchanged.…”
