Localized operation and implementation

Compared with centralized and distributed control, local control has significant advantages of high computation efficiency and robustness to address the distributed generators (DGs) uncertainties. In this chapter, a local control framework is formulated to realize the effective implementation of operational strategies. First, the local control strategies with a high share of DG are proposed, in which a parameter-tuning model of control curves is built to improve the control performance. The model predictive control-based local control strategy is further proposed to reduce the high computation and communication burden. Considering privacy preservation, a cloud-edge collaboration-based local control strategy for DGs is proposed without accurate network parameters and entire flexible distribution network data. Finally, a combined centralized and local control strategy of soft open point (SOP) is further proposed. Regional autonomy and collaboration with local information are adopted to address operational issues.
