This paper proposes an online clustering modeling method for photovoltaic (PV) power plant considering low voltage ride-through (LVRT) control. The proposed method takes the distance of the unit impulse response curves of the inverter controllers as the clustering index to build the clustering models of the inverter controllers. After all LVRT controllers are simplified and described by an equivalent...
A multi-stage Active Distribution Network (ADN) planning model that integrated with the application of Energy Storage System (ESS) is presented in this paper. Both the longterm investment cost and short-term operation conditions of ADN are considered in the proposed model. The benefits of power supply reliability improvement brought by ESS in the ADN are also included. In each planning stage, the...
This paper presents a simplified photovoltaic array model to describe the photovoltaic system features under partially shaded conditions. Based on the proposed model, the peak power sliding phenomenon of photovoltaic generation is studied during the above mentioned system dynamic process. The paper analyzes the mechanism of the peak power sliding and the critical sliding conditions. Simulation cases...
