| 摘 要： | 为更好地实现端对端电力交易，提出了二级聚集式控制策略。该策略只需一个数据监测点和从监测点到产消者的单向通信就能够实现端对端电力交易。其中，第一级控制采用带约束的非线性优化，以最小化社区微电网电费为目标，第二级控制采用基于规则的实时控制策略。通过仿真算例验证了控制策略的有效性，并对比分析了在社区微电网中采用集中式和分布式蓄电池对电能损耗及电费的影响。

| Abstract: | The variation of fossil energy consumption, carbon dioxide and pollutant emissions are calculated after conventional fuel vehicles are replaced with electric vehicles based upon the full-cycle energy efficiency theory. The results show that the primary energy consumption, CO2, CO and HC emissions can be reduced with the substitution of electric vehicles for petrol vehicles, but NOx and SO2 emissions are increased. When diesel vehicles are replaced with electric ones, the emissions of pollutants except SO2 will be reduced, but the total emissions of CO2 and SO2 will be increased. Considering the proportion of coal-fired power generation to the total power generation in China, the target of energy saving and emission reduction cannot be thoroughly realized by the substitution of electric vehicles for oil-fired vehicles. |
