基于蒙特卡洛模拟的PHEV充电策略研究

o control the great impact that a large number of PHEVs' freedom charging bring to the distribution network. Based on Monte Carlo simulation, calculated the PHEVs' freedom charging load, the results show that a large number of PHEVs' freedom charging will largen the difference between the peak and valley load, and cause the distribution network voltage to get across the limit. A delay charging strategy considering the battery capacity was proposed, this strategy consider the relation of the peak load and the PHEV's battery capacity, the delaying time and the truncation time. As an example, calculated the IEEE 33 nodes system, the results show the proposed strategy can meet the charging requirements, reduce the difference between the peak and valley load, and improve the voltage level.
