Abstract

As the needs of human life increase, the need for electrical energy will also increase. Currently, fossil energy, which is widely used as fuel for the provision of electrical energy, is running low. In Indonesia, renewable energy sources have not been utilized properly, such as wave energy. This study discussed how to design a prototype of a sea wave power plant. The problem is, how to be able to utilize the energy of sea waves to the maximum. The purpose of this research is to find solutions and designs to utilize recoil starter as a prototype of ocean wave power plants. The methodology used in this study is an experiment in which the prototype made is given a certain treatment and then measurements are made. His data analysis technique is descriptive analysis. Based on the results of measurements and observations, the performance of the tool is not only influenced by the height of the wave, but also the period of arrival of the sea wave and the ballast load of the tool. After measurements were made on the first day of Maruni beach, the prototype could produce an average power of 4.21 watts for an average wave height of 0.35 cm and Maruni beach on the second day could produce an average power of 5.68 watts for an average wave height of 0.4 m. While on the first day Amban beach obtained an average power of 3.29 watts for an average wave height of 0.37 cm and Amban beach on the second day could produce an average power of 14.26 watts for an average wave height of 0.5 m.

Abstract

This paper presents a techno-economic assessment of integrating engine power plants into a power grid, using the snake optimization (SO) algorithm to solve the multi-objective optimal power flow (OPF) problem. The study focuses on four key objectives: minimizing fuel costs, reducing voltage deviation, enhancing voltage stability, and minimizing active power losses. Simulations conducted on the 38-bus of Manokwari grid system demonstrate that the SO algorithm significantly improved performance in all areas. Fuel costs were reduced to 2.003 million USD/h while maintaining a stable voltage profile. Voltage deviation was reduced to 0.5577 p.u., ensuring better voltage consistency across the grid. Voltage stability was enhanced with a minimized Lmax value of 0.0200 p.u., and active power losses were reduced to 0.3423 MW, reflecting a notable increase in system efficiency. These findings demonstrate the effectiveness of integrating gas engine power plants, which led to noticeable improvements in operational efficiency and grid stability.
