Optimal Planning and Performance Analysis of Hybrid Energy System for Oil Tanker Ships

Nowadays, owing to the growing worries about the environmental pollution caused by conventional ships, the usage of renewable energy sources along with energy storage in ship power systems is gaining a lot of attention. However, improper design of these alternatives will cause increment in investment costs and pollutants emission. In this regard, this study proposed an optimal approach for designing a standalone electrical system for an oil tanker ship sailing from Colombo port to Haldia port. The main objective of this study is to minimize both investments cost and pollutants emission cost. The different operation conditions are considered to model the ship’s electrical load. Moreover, the uncertainty associated with solar irradiance and wind speed along the navigation route is taken into account to formulate the mathematical model. Furthermore, the proposed problem is solved by an accurate and computationally efficient crow search algorithm (CSA).
