Reducing Substation Demand Fluctuations Using Decoupled Price Schemes for Demand Response

摘要

A method reduces substation demand fluctuations using decoupled price scheme to mange load flexibility to follow renewable variations in a power distribution system. The price scheme includes base energy price component, up/down reserve usage price component, and up/down reserve usage variation price component. The operator adjusts the corresponding price components to achieve desired aggregated demand profile at a substation. Meanwhile, the operator determines the optimal amount of reduced loads, removed loads and transferred loads to minimize the total cost of substation power purchase, available but unused renewable penalty, and demand responses.
