RESUMO

A successful restoration depends on the quality of the restoration plans, that describe the sequence of control actions that must be executed to reenergize different areas (of the power system) just after total or partial blackouts. This work proposes a methodology to automatically evalute the quality of power system restoration plans, related to (a) the flexibility of the plan, (b) numerical quality indexes, extracted using a graph representation for the plan and (c) the easiness of use, visualization, training and access to restoration instructions. Different techniques and methods were used to achieve this goal (minimum path search, adoption of fuzzy indexes, critical path methods), focusing on the determination of numerical indexes that express the quality of the plan, such as total restoration duration, fluent phase efficiency, interrupted load evolution and estimated interruption costs
