Optimal Power Flow (OPF)

Definition

Optimal Power Flow (OPF) refers to a mathematical optimization approach used to determine the most efficient operation of a power system while satisfying a set of constraints. This process helps in minimizing operational costs, improving system reliability, and ensuring that power generation meets demand, all while taking into account various factors like generation limits, transmission capacities, and environmental considerations. OPF is especially crucial for optimizing microgrid operations and energy management strategies, where localized energy production and consumption can be optimized for cost and efficiency.
