“…In addition, some other hydroelectric dams, such as Batang Ai (108MW) and Murum HEP (944MW), generate electricity for domestic usage. Meanwhile, many remote areas still do not have electricity accessibility [4] . To solve this problem, proper identification and integration of new locations of HES are necessary [5] .…”

“…Due to the location that are remote from the electrical grid as well as the variable tropical climate in Sarawak, the community living in these rural places experienced limitation of accessibility to modern world due to the limited accessed to electricity. Therefore, diesel generator powers used for their daily electricity, however the usage of diesel generator cause a high electricity production cost and diesel transportation issues [1]. Other than that, different types of renewable energy resources (RES) for example micro-hydro turbine system also being used as electricity sources in the rural area with large number of users [1,2].…”

“…According to Datuk Seri Dr Stephen Rundi Utom, the State Utilities Minister, Sarawak state government target to achieve full electrification by 2025. However currently up to 30,400 households in rural areas had yet to enjoy 24-hour electricity supply [1]. Due to the geographical constraints in installing transmission and distribution to transmit electricity to rural areas, the implementation of renewable energy sources (RES) is the best option since these areas have low demand of load usage [3].…”

In the past few decade, longhouse communities in the rural area of Sarawak has been experienced the limitation of electricity supplies. Due to geographic of Sarawak, supply electricity to these rural areas from utility grid through transmission lines also will only results in many losses, the initiation of utilize solar as prime sources is favourable solution. The implementation of DC microgrid system for this area will achieved, as the solar PV system is a DC source to generate electrical supply for appliances in longhouse communities. However, the tropical climate and geographical in Sarawak such as the inconsistent solar radiation, changing temperatures, high humidity and heavy rainfall will be the main restrain to implement solar DC microgrid system. Thus, this paper proposes a comprehensive study about the voltage distribution of DC microgrid configuration in order to investigate system the reliability and efficiency. The configuration of DC micro-grid model has been designed using MATLAB Simulink and an experimental presenting the Simulink also has been developed for validation purposes. The obtained simulation and experimental results confirm that the proposed configuration of the ring system with multiple-sources is more reliable and efficient than radial system with multiple-source configuration in terms of DC voltage distribution at different buses. Thus, the proposed configuration is more reliable according to voltage distribution at each buses.

“…According to the statistics provided by the Ministry of Public Utilities, in 2010, the percentage of electrified houses in the rural areas of Sarawak was approximately 78%. This implies that a large number of electricity users in the remote villages have the potential of obtaining electricity through the main utility grid, while others can only get electricity by installing different types of RESs [3]. In fact, consumers living in the rural areas of Sarawak are experiencing limited access to electricity; this is due to the geographical difficulty in installing transmission and distribution systems to deliver electricity from the main grid, as such systems must pass through rough terrain and dense jungle.…”

In the past few years, the prime focus of supplying electricity to the longhouse communities in the rural areas of Sarawak has been initiated based on the utilization of a single-source microgrid configuration. The existing AC power supply-based solar photovoltaic (PV) systems in these areas pose many problems, mainly owing to the stages of conversion, energy losses, and the quality of power transfer. As the solar PV system is a DC source and most of the appliances in longhouse communities could be operated using DC source, an opportunity to design a microgrid with high reliability and efficiency would be achieved by the implementation of an optimal DC microgrid configuration. With this aim, the paper proposes a multiple-source DC microgrid configuration for the longhouse communities in Sarawak. Initially, a framework has been developed to design simulation models for both microgrid configurations (single and multiple sources) using MATLAB Simulink. The configuration of each system consists of a solar PV and energy storage to form a standalone microgrid. Due to the change in system configuration of DC microgrid, in the modeling approach, the standard power flow equations are modified to include solely the DC parameters. To validate the proposed configuration with the associated modeling approach in terms of the power flow reliability, system efficiency, and power-voltage curve, an experimental setup representing the Simulink model has been designed for each standalone microgrid configuration. The configurations have been assessed in the same location with different daily weather conditions. The obtained simulation and experimental results confirm that the proposed configuration of multiple sources is more reliable and efficient than the existing single-source configuration.
