Abstract: Escalating stratums of breeze vigor, which is variable, difficult to predict accurately, and escalating connected via power electronic converters, are changing how electricity grids are planned, designed, and operated. . Systems with high breeze penetration are also experiencing dramatic changes to the operating regimes of conventional resources to areas with large loads. Optimal diminutive-tenure (minutes to day ahead) vigor harmonizing for systems with high breeze penetration, which is the focus here, requires high-quality breeze forecasts and advanced scheduling methodologies. These advances from the traditional scheduling approach include: dynamic reserve targets, higher resolution scheduling periods, more frequent scheduling, and the use of stochastic optimization techniques. Here, some of the possible evolutions in optimal diminutive-tenure vigor harmonizing to better deal with breeze vigor uncertainty are investigated. The focus is mainly on managing reserves through changes in scheduling, in particular market structure (more regular and higher resolution scheduling), reserve procurement (dynamic as opposed to static), and improved operational planning (stochastic as opposed to detenureinistic). Infrastructure changes including flexible plant, increased demand side participation, more interconnection, transmission, larger harmonizing areas, and critically improved forecasting can also be significant and are dealt with in the discussion. The evolutions are tightly coupled, their impact is system-dependent and so no best set is identifiable but experience of system operators will be critical to future developments.
