Optimization of Smart Energy Systems
ABSTRACT
The course provides students with mathematic modeling of SES components. Base on the models, optimization methods for SES will be deducted. The solutions for power flows optimization, system reconfiguration optimization, system operation will also be analyzed to get SES better performance and response.
The goal of the course is to equip the student ability for understanding, performing and analyzing optimal power flows as well as optimal operation of SES. Base on the analysis, the optimization of system reconfiguration in order to achieve a single or multiple user-specified objectives (like economic dispatch) should also be obtained.
The course is also objected to select appropriate optimizers /criteria (local vs global ones) for single or multi-objective problems in Power systems.
After finishing the course, students should also have competencies to select the optimal operation modes of SES in both normal and abnormal situations.
