Generation Units Maintenance Scheduling in Multi-Carrier Energy System

In medium-term planning of mult-carrier energy systems, the operator is required to schedule the outage of units for maintenance. The Main challenging is that there are concurrent resources in the system. These concurrent resources play key role in energy generation networks. In this paper, the scheduled maintenance is done in order to minimize the costs in the medium term while the reliability of multi-carrier systems and supply reliability is preserved. The proposed framework includes a bi-level programming model. The objective of the proposed model in the higher level is to minimize operating costs in the medium term and at the lower level, the objective is to maximize the reliability indices with corresponding constraints. The proposed model is tested on a local Multi-carrier System (Special Economic Zone in Assaluyeh), and the simulation results indicate that coordinated outage window unit, is more reliable than the separated scheduling models and therefore highlights the need to fix the models conventionally utilized by independent programming networks.
