Despacho Ótimo de Microrredes: uma Comparação dos Métodos de Otimização Distribuída de Consenso, Difusão e Difusão Exata

Abstract

Microgrids aggregate technologies that represent the main drivers of a disruptive transformation in the energy sector: decarbonization, decentralization and digitalization. The distributed and varied nature of the energy resources of a microgrid promote the fragmentation of the electric sector value chain, making the optimal dispatch more complex. In this regard, this paper presents three distributed optimization methods, Consensus, Diffusion and Exact Diffusion, applied for the solution of the optimal dispatch of an islanded microgrid. The methods are enhanced in order to ensure better performance and balance among generation, demand, and energy storage. The optimization approaches have demonstrated suitable results with emphasis to the performance of the Diffusion and Exact Diffusion methods, which have been little explored in the literature so far and have presented a considerable efficiency gain to microgrids optimal dispatch purposes.
