Abstract

Among several types, variable speed-based wind turbine generator (WTG) is the most popular type installed worldwide. This type of WTG is able to extract 5% more energy from wind speed compared to the fixed speed WTG. There are two kinds of variable speed based WTG; Doubly Fed Induction Generator (DFIG) and Full Converter Wind Energy Conversion System (FCWECS). DFIG and FCWECS are placed at the first and second topWTG installation worldwide since 2004. However, both of them are very sensitive to the grid dip fault and may violate the allowable margins identified by various international Fault Ride Through (FRT) codes. This paper aims to investigate the responses of DFIG and FCWECS during certain level of grid dips and compare their performanceunder such event. Results show some differences of the performance of DFIG and FCWECS during voltage sag event, however the voltage profile at the point of common coupling is much better in case of DFIG. Results also recommend that DFIG can be effective when connected to weak grids whilst FCWECS is preferably to be connected to strong grids.

Abstract

As an enabler component for renewable energy integration, power electronics (PE) technology in smart grid system is one of the most important issues of development the electrification, decentralization and information-technology/operation-technology (IT/OT) digitization within the electrical energy transmission and distribution systems. The arrangement of PE may different along the feeder either for grid-connected photovoltaic (PV), wind turbine, fuel cells, wave energy system and battery storage unit, respectively.This is due to the electric voltage that might need to be converted from alternating current (AC) to direct current (DC) and vice versa. For that reason, this paper proposed a concept of advanced PE as an integrated arrangement of several AC/DC/AC-and DC/AC- converters in such ways that support thepreviously mentioned grid-connected hybrid renewable energy sources and distributed generators (DGs) along the distribution feeder. Additionally, for the system that supported by battery storage unit, then this hybrid smart grid concept might become the answer for future utility needs.

Abstract

Installing rooftop Solar Power Plants (SPP) represents the most efficient solution for reducing substantial electricity consumption in office buildings and hospitals, as Makassar Eye Hospital exemplifies. The research commences by addressing concerns about electricity availability and daily usage at the hospital while evaluating the solar radiation potential. Subsequently, the development of the SPP system begins. A location assessment is conducted using various tools to gather the necessary data for SPP design. In this study, the planning phase involves the utilization of PVSyst software for the technical analysis of electrical energy generation and system performance calculations. Additionally, the economic analysis includes evaluating the initial investment costs for establishing the SPP and considering prevailing market prices for components. The feasibility of the SPP investment is determined by calculating key financial metrics, including the Payback Period (PP), Net Present Value (NPV), Internal Rate of Return (IRR), Profitability Index (PI), and Return on Investment (ROI). According to the economic analysis findings, the initial investment cost for the SPP amounts to Rp. 544.031.733. The energy production value per kilowatt-hour (kWh) stands at Rp. 1.278, resulting in a Payback Period (PP) of 13,8 years, a Net Present Value (NPV) of Rp. 138.182.638, an Internal Rate of Return (IRR) of 11.51%, and a Return on Investment (ROI) of 25.4%. These results affirm the plan's feasibility, as the IRR value surpasses the Discount Rate (8.43%).

Abstract

On one hand, the particular objective of this research is to yield the software program in order to control efficiently the important aspects in electric power systems which can be implemented in industries. In the other hand, the longterm objective is to extend the curriculum, syllabi, laboratory facilities, and to improve the abilities and qualities of graduates continuously either within State Polytechnic of Ujung Pandang or outside. Method used to achieve these objectives is making, design and implementation which will be last for two years. Simulator for generation system in the first stage of the research is balanced six-phase system yielded from the circuit of 3-one phase centre-tap transformers of 220/18 V, 15 A, as the supply of low-tension 3-phase system, which feeds six one-phase transformer of 18/220 V, 20 A, whose output as another balanced 3-phase system with 220 V/phase. From balanced 6-phase system, a balanced 3-phase will simulate generator number 1 and another balanced 3-phase will simulate that of number 2. Interface which is based on Delphi program is to switch all transmission lines. The result of experiment shows that voltages in the two generator busbars experience the significant drop voltage if they work separately, that are 20.5% - 36.4% and 20.5% - 63.6% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also reveals that greatest voltage drop occurs in the generator busbar with most lines supplied. Simulating the two generators working simultaneously, then voltage drops are more significant, that are 65.9% - 72.7% and 65.9% - 79.5% for generator number 1 and number 2 respectively, for one to three load busbars operated sequentially, which also proves that transformer bank as generator simulator needs to increase its current capacity.

Abstract

Savonius wind turbine is one of the wind turbines that is more widely used for low energy needs, with more energy needs, this turbine type is very feasible to be developed. This research aims to improve the performance of Savonius wind turbines with variations in turbine blade curvature and variations in wind speed. The research method is a laboratory experiment on the fan test, the blade curvature test variation is 1R; 1.5R and 2R, another variation is the wind speed which are 4.0; 5.5; 7.0 and 8.5 m/s. The experiement results shows that the greater the wind speed, the input power, air mass flow velocity, power output, and efficiency will be even greater; the greater the load force on the turbine shaft, the torque on the turbine shaft will also be greater; the relationship of force loads to power output and turbine efficiency is to construct a parabolic curve; for the same wind speed, the 2R turbine has the lowest rotation, power output and efficiency compared to the 1R and 1.5R turbines; at the same wind speed the 1R turbine produces a higher rotation but requires lower torque than the 1.5R turbine; at low wind speeds (4 m / s) the 1.5R turbine has better efficiency than the 1R turbine, whereas at the high wind speed (8.5 m/s) the 1R turbine has a better efficiency than the 1.5R turbine; The maximum efficiency is obtained at 89.56% in the 1R curvature turbine with a wind speed of 8.5 m / s.

Abstract

Balang lompo Island is supplied by Diesel Power Plant (DPP) and Solar Power Plant (SPP), in the operation of SPP it is considered not optimal due to the amount of solar panel capacity of 200 kWp while MPPT capacity of 120 kW and inverter capacity of 100 kVA, with these conditions the research was carried out with the aim of optimizing the generating system on Balang Lompo Island. The optimization of the generating system is conducted by simulation using Homer Legacy Beta software. By entering several important parameters such as technical, economic, and environmental factors therefore, the simulation results obtained in the form of the most optimal system operating patterns represented by one of the smallest net present cost (NPC) parameters, and also the recommended operating hours between DPP and SPP. The research method employed are the preliminary study research, identification and formulation of problems, data collection, data processing using Homer Legacy v2.81 Beta software, and analysis of the simulation results. In this study there are two conditions are compared, the first condition is the existing condition with an MPPT capacity of 120 kW and an inverter capacity of 100 kVA and the second condition is the addition of MPPT capacity to 200 kW and an inverter capacity of 200 kVA. Based on the results, it can be concluded that with the addition of capacity in SPP equipment, namely MPPT capacity to 200 kW and inverter capacity to 200 kVA, it is proven to be able to save NPC costs, O&M costs, fuel costs, reduction in DPP operating hours and DPP fuel consumption. With an NPC value of US $ 3,362,929 (IDR. 48,957,520,382), with the implementation of this system the NPC cost savings could reach US $ 197,161 (IDR. 2,870,269,838) during the 25-year operating period, and savings in US fuel/HSD consumption costs $ 23,936 (IDR. 348,460,288) per year.
