Generation Units Maintenance Coordination in Multi-Carrier Energy System

In the mid-term operational management of multi-carrier energy systems (MCES) in a deregulated system, coordination among owners of production units is very important. Scheduling the CCHP resources and also the behavior of the owners of production resources are the main coordinating challenges. The cogeneration resources play a key role in energy generation networks and are affected by the behavior of the owners and their operation policies. In this paper, a model is presented that coordinates resources  in MCES in competitive conditions. It takes the objectives of key players, including system operator into account. The proposed model is a multi-objective model and aims to minimize mid-term costs for the resource owners and ensures the reliability of the network over the medium term from the perspective of the operator of the whole system. To solve the multi-objective problem, the Epsilon-constraint method has been used and the Pareto front has been solved. The Fuzzy method was used to find a unique answer to the problem. The proposed model is tested on a local MCES (Special Economic Zone in Assaluyeh), and the simulation results indicate that coordinated outage window, eliminates the scheduling challenge for the output of concurrent production units in these networks.
