Due to the power peak load shifting, flexible load has considerable schedulable potential and could effectively improve the active distribution network (ADN) operation. After analyzing the scheduling mode and response characteristic of two typical flexible loads, this paper proposed a model for multiperiod service restoration in ADN with flexible load participated. On the basis of flexible load interruption...
Load shedding is an efficient solution to improve power system reliability when a contingency occurs. Considering loads difference has great significance in the process of load shedding. This paper proposes a new minimum load shedding calculation approach based on multi objective optimization theory. The load shedding model proposed in this paper considers the loads difference and introduces the importance...
This study, considering the probability load growth and load distribution imbalance, proposes a mathematical model for city total supply capability (CTSC). First, it introduces the concepts to CTSC and available load supply capability (ALSC); second, using multi-scenario method to analyze the future load, so it could get some possible load scenarios; then the model is translated into linear constrained...
With large-scale electric vehicles penetrating into power system, the grid will be faced with severe challenges. Accurate charging load forecasting is required to ensure the security and economy of the grid. Firstly, the factors that influence the daily load of electric bus stations are analyzed in this paper. Based on the grey relation theory, samples of similar days are selected to establish SVM...
Currently the development of large scale electric vehicles have become governments' focus of attention. Based on the research of charging and discharging power models, the paper puts forward the island formation strategy and establishes the distribution system reliability model with the electric vehicles. The Monte Carlo time sequential simulation is used to evaluate the effects of different vehicle...
