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.

In this study, we will investigate the possibility of using renewable energy resources in area where electrical energy is not supported. We will consider it as a micro-grid and we will try to supply its electrical energy by decreasing cost and having reliability in system. Generally, the main reason of designing and developing of distribution grid is responsible to growth of electrical consumption with maximum economic efficiency which the restriction of system is not made violation. Existing more elements in the distribution and sub-transmission networks have faced the designing and developing with problem where there are many decision variables. Advert of the distributed generation in distribution systems furthermore the changing operation of these systems provide this possibility to companies that can design systems with low cost. In this study, we aim to minimize the cost of the hybrid system of hydroelectric, wind, solar and battery and we will calculate LPSP index by GSO algorithm. It is designed and implemented for long-term network over 20-year.
