Coordinated voltage control scheme for distribution grid with on-load tap-changer and distributed energy resources in a market context

摘要: The evolutionary changes in the electricity system are reshaping operation and control to achieve a more sustainable environment. In this transition, distributed energy resources (DERs) may introduce some problems, such as intermittent features, but could also play an important role on accommodating intermittence assisting operation. A proper aggregation coordination scheme of DER units is required enable flexibility provision economical efficient manner. meanwhile, nondistruptive essential guarantee their long-term active participation. addition, newly established should allow coordinate other controllable grid facilities. This paper proposes hierarchical operating framework for assets market Voltage regulation common service used case study. necessity between facilities, e.g., on-load tap-changer (OLTC), addressed.
