  • Publication number: 20180375373
    Abstract: The present invention discloses an impact increments-based state enumeration (IISE) reliability assessment approach and device thereof. The method includes: inspecting the accessibility of all elements of the independent adjacency matrix by the breadth-first search method; if there is inaccessible element, the impact increment is zero and the power system state is reselected; if there is no inaccessible element, evaluating the impact of the power system state under all load levels via optimal power flow algorithm, acquiring the impact expectations of power system state under different load levels, and then acquiring the impact increments of the power system state; acquiring the reliability index of power system by impact increment when all the centralized power system states have been analyzed and the maximum number of contingency order has reached.

  • Publication number: 20180240047
    Abstract: A planning method of EV fast charging stations on the expressway, comprising the following steps: Step 1: forecasting the spatial and temporal distribution of EV charging load, that is to determine the time and location of each EV needing charging on the expressway; Step 2: based on the forecast result achieved by Step 1, determining the locations of the fast charging stations on the expressway by the nearest neighbor clustering algorithm; Step 3: according to the spatial and temporal forecast result of the EV charging load and the locations of the fast charging stations, determining the number c of the chargers in each fast charging station by queuing theory. Due to battery characteristics, traditional gas stations do not completely match the fast charging stations.
