Microgrid systems are becoming more popular and the main component in a microgrid system is generation, which in a microgrid system usually consists of distributed generations (DGs). Because the renewable energy (RE) generators are an inverter-based generator, a microgrid dominated by RE generators is called inverter-based microgrid. Due to intermittency of RE generator, such as solar PV, the RE power generation variation may cause instability. The conventional method to analyze system stability due to the variation of loads and generation is modal analysis. In this experiment the proposed method for analyzing small signal stability is by using Kharitonov's Theorem. The objective of this experiment is to analyze inverter-based stability using Kharitonov's Theorem and compare it to the result using conventional analysis method which is modal analysis. Using Kharitonov's Theorem, the system stability can be determined for several operation scenarios within certain time range. In this experiment, the inverter-based microgrid will be modeled using DIgSILENT powerFactory and the system matrices will be exported into MATLAB software to be analyzed and converted to four transfer functions using Kharitonov's Theorem. The four output transfer function will determined the system small signal stability of modeled microgrid in one day operation. © 2023 IEEE.

The swift progression of industrial technology underscores the need for adept professionals capable of skillfully implementing and managing intricate systems. Vocational education assumes a pivotal role in cultivating competent intermediaries proficient in translating theoretical knowledge into practical applications. At the core of industrial automation lies the programmable Logic Controller (PLC), a specialized digital computer that interfaces with sensors, switches, and actuators to execute real-time control programs, thus facilitating meticulous industrial processes. This study concentrates on the practical deployment of a two-floor elevator system utilizing the OMRON CP1E N30 PLC. Elevators, integral to contemporary structures, mandate precision for secure vertical conveyance. Leveraging input signals from elevator buttons, sensors, and switches, the PLC orchestrates efficient motor control and dependable door operations. This hands-on application underscores the PLC's significance within real-time control contexts. Nonetheless, Vocational Higher Education graduates frequently grapple with the challenge of transitioning to industry settings due to limited practical exposure. This partnership harmonizes with the center's objective of enriching vocational education by integrating sophisticated technologies like PLCs, equipping the workforce with the acumen to bridge the gap between theoretical foundations and the pragmatic demands of industry. © 2023 IEEE.

Development program for construction of irrigation channel gives big opportunity for development of renewable energy from small low head hydropower source. The use of hydropower gives no negative impact to environment, especially for greenhouse emission. A gravitational vortex hydropower is the object of this study, with the focus on the water intake channel using rectangular geometry. An experimental study was conducted to find the influencing parameters on the intake section of the gravitational vortex hydropower. A set of parameters were varied to determine which parameters affecting the water surface at the intake channel. By analyzing the results of the experiments, the influence of parameters on the water intake channel of gravitational vortex hydropower was found. A performance curve for differentiation of flow type and identification of surface contour has been made. Based on the results of the experiment, placing a strainer at 5 cm distance gave 60% higher output power since this setting could reduce the wave speed. Recommendation to have further study in non-dimensional parametric should be considered for increasing efficiency of the gravitational vortex hydropower. © 2020 IEEE.

Energy demand is increasing and it raise a climate change issue. Greenhouse emissions, depleted fossil energy resources, increasing fossil energy cost are reasons to maximize the utilization of renewable energy source. Hydropower extend an alternative energy source to cover the growing energy demand and release no emission at the same time for maintaining the climate change. In recent years, major focus of hydropower research is moving to small hydropower, as large hydropower opportunities are exploited and have high capital expenditure to build. A water vortex stream is a common phenomenon that we can see everyday life. Water flow out from the bathtub through outlet or water flow down in the sink after we finish washing the dishes, that is what we call vortex flow. and is a free-surface flow, homogenous fluid that contained water and air. This water vortex can be applied in low head small hydropower plant, recently known as gravitational water vortex power plant. River off Gravitational Water Vortex power plant (GWVPP) is one of low head turbine that can be used to generate electricity in small scale, pico-hydro. This study is focus on basin geometry. Models are developed to investigate the outlet diameter, depth discharge and basin geometry. It is found out that parameter of the basin should refer to source, which are flow rate, and the head of the water. It shows that spiral geometry for the basin gives symmetric and strong vortex and can be used as an alternative of conical basin. © 2020 IEEE.

International Conference on Science and Innovated engineering 2018, i-COSINE 2018

作者： Yunus, A. M. Shiddiq Swasti, Sri Purwito Energy Conversion Study Program Mechanical Engineering Department Politeknik Negeri Ujung Pandang Indonesia Electric Power Engineering Study Program Electrical Engineering Department Politeknik Negeri Ujung Pandang Indonesia

This paper presents an overview of the Hysteresis Current Controller (HCC) application in Renewable Energy Based power System. The beginning concept of HCC is considered to be formally introduced by Thomas M. Freederiksen and Ronald W. Russel in 1971 that was registered in US Patent No. US3725673. The fundamental principle of HCC is based on the comparison of the instantaneous load current to the instantaneous sine wave reference where the difference between the two is maintained within the defined upper and lower band. There are some advantages of using HCC including simple, insensitivity to load parameters variations, fast dynamic response and inherent maximum current limiting characteristics. Therefore, based on its robustness, HCC has currently applied also in renewable energy based power plants such as PV converter system, power Electronics System of Wind Energy, and in SMES control system for Wind Energy Application. However, the drawback of HCC system was also discussed in some papers compared with other control systems, for instant HCC is giving high chattering in torque in IM drive test. Therefore the combination of HCC with other controllers also becomes a new trend to improve the applied system that involving HCC as the main controller. © Published under licence by IOP Publishing Ltd.

Significant population and economic growth, caused increasing of energy demand. Depletion of fossil fuel moreover coupled by climate change issue that caused by increasing carbon emission, become necessity to continuously encourage achieving renewable energy mix in energy primer. Large potentials of hydro renewable energy source and small utilization of it, micro-hydro and pico-hydro power plant are suitable to develop especially in country side. The research gap in the current turbine application chart is a challenge for Gravitational Water Vortex power Plant (GWVPP) strong existence in pico-hydro power, besides conventional turbine design has been developed into it. However, development in vortex flow and basin geometry design has a robust design for the past 10 years of research. Researches have been conducted in few countries that proofed GWVPP has less capital investment and low operational and maintenance cost, however the parameter of the GWVPP still need further development since the power output efficiency still low. Since basin opening and outlet diameter are the main parameters to define basin geometry, inlet channel need to do further research. The research will improve the recent gaps;therefore, vortex turbine could be developed accordingly that would result immediate improvements for renewable energy growth in Indonesia through GWVPP. © 2020 IEEE.
