Melhoramento da Resiliência em Sistemas de Distribuição de Energia Elétrica Usando Alocação de GD e Sistemas de Armazenamento de Emergência Móveis

Abstract

This paper presents a planning and operational strategy to improve the recoverability of the distribution systems (DSs) against a set of possible line fault scenarios. Within this strategy, the planning actions consist of allocating dispatchable distributed generation (DG) units while the operational actions include the complete dynamic restoration process. The restoration process considers the radial system reconfiguration and islanding operation, all while simultaneously considering the pre-positioning and displacement of mobile emergency storage units. The proposed strategy is formulated as a single objective stochastic scenario-based mixed- integer linear programming model, considering uncertainties associated with the solar irradiation and demand consumption in a multi-period formulation. The objective function minimizes the investment cost of new dispatchable DG units and the amount of energy shedding within the system. The proposed model is validated using the 33-node DS under different cases and results show the benefits of simultaneously solving the planning problem with a restoration process.
