考虑线路拓展的交直流混合微电网规划研究
|
摘要
针对交流微电网规划问题,建立考虑微电网线路拓展的优化规划模型:以投资成本、运行维护成本、购电成本及系统损耗最小为优化目标,考虑系统功率平衡、系统支路数、分布式能源出力、节点电压偏差等约束条件,基于JAVA平台建立相应的数学模型,调用Cplex行拓展时,交直流混合微电网具有一定的竞争性。
Aiming at the problem of AC microgrid planning,an optimal planning model considering microgrid line expansion is established. The main objectives are minimizing investment cost,operation and maintenance cost,power purchase cost and system loss. Considering the constraints of the system power balance,system branch number,distributed energy output and node voltage deviation,the corresponding mathematical model based on JAVA platform and applying the Cplex optimization software to solve the model is established. The actual engineering examples showed that AC/DC hybrid microgrid has a certain degree of competition when extending the existing AC microgrid.
