“…It is important to say that the energy should be transferred in the distributed network considering the communication platform. The detailed data of the WT and tidal units represented in the AC network are taken from [24], [25]. Also, the electrical grid is provided based on the IEEE 24-bus test system and the data of the hub system have coincided with the proposed hub system in [24,26].…”

“…The objective function of the grid can be defined based on reducing the operation cost of the active power of generators, start-up and shut-down cost for generators. All constraints of the electrical grid are followed in (21)-(32) in which the constraint (25) shows the active power balance between the generation and demand. The T t P variable is represented as the injected power from the electrical grid to the AC bus of AC network.…”

The ongoing development of technology has changed the nature of electric networks in the field of electric power generation. In the same vein, the generation units and demands are getting close by the integration of distributed resources within the distribution system with the aim of bringing more advantages to the system. Considering the promising concept of hybrid networks, which comprises different distributed resources, as a supportive element for the power system, this paper mainly focuses on modeling a distributed hybrid network, through which both the AC and DC loads can be supplied within the hybrid network. This network is operated in a distributed way where no independent operator is assumed for the operation. The primal-dual method of multipliers (PDMM) as an effective distributed method handles the operation of this network. So far, this method has only been applied to the AC grid or DC grid separately, while the presented method is modified for the operation of the hybrid network. Convergence speed and preciseness are mentioned as the advantages of this method which dominates the alternating direction method of multipliers (ADMM). In real cases, there are some errors in the output power of the renewable resources. Aiming to make the presented PDMM method more applicable, the uncertainty is also modelled using the Unscented Transform (UT) approach, as a way of uncertainty modelling which has shown attractive features, especially the capability of correlation modelling; therefore, it is more preferable for uncertainty modeling in many cases compared to the other methods. The proposed work is implemented on a smart island and the authenticity of this work is proved by comparing the performance of the proposed distributed approach with the centralized method.

“…This may result in results which are not much trustable by ignoring the weather conditions. In [22], the security constraint UC is solved incorporating the TS and reliability of circuit breakers. Due to the non-linear nature of the circuit breaker and its dependability on the number of switching, a linear model was developed to linearise the model.…”
