Power generating systems

In this paper, the IMPSA wind turbine based on variable speed wind generators is considered. The article ends with a validation of the stable Ninh Thuan – Binh Thuan grid model generated by PSAT including a new variable speed wind turbine model. This validation is done through an eigenvalue analysis by applying small disturbances from wind speed variation.

The modernization of the world has considerably reduced the prime sources of energy such as coal, diesel and gas. Thus, alternative energy sources based on renewable energy have been the main concentration nowadays to address the world’s energy demand as well as restrict global warming. Solar energy is the main source used to generate electricity through photovoltaic (PV) system. However, the output of PV power is normally intermittent.

This study suggests a solution to the ELD problem based on a new intelligent optimization algorithm called the Jellyfish search algorithm (JSA). Due to the imitation of jellyfish's behavior searching for food in the ocean, the JSA owes the advanced characteristics, e.g., simple structure, fast search, and easy to implement. The ELD problem is mathematically expressed as a typical multi-constraint nonlinear optimization problem that can be dealt with by optimizing the JSA algorithm successfully.
