Refined Configuration and Evaluation of Distribution Secondary Equipment Considering Controllability and Observability

Under the background of new power system， the difficulty of distribution network control and observation has been significantly increased. However， the existing research on controllability and observability of distribution network and the corresponding distribution secondary equipment planning models cannot meet the needs of actual control and observation of distribution network. Therefore， a refined configuration model and evaluation method of distribution secondary equipment based on controllability and observability analysis are proposed. Firstly， complete mathematical definitions of distribution network controllability， observability and related indicators are proposed. Secondly， the mapping set of controllability and observability demand to state variables is constructed. Finally， refined planning model and multidimensional evaluation method of distribution secondary equipment are proposed. The example analysis shows that the proposed planning and evaluation method achieve the maximum of comprehensive benefits with the minimum economic cost， which proves its feasibility and effectiveness.
