摘要: |
针对分布式电源在配电网中不断增加及其波动性和间歇性对电网稳定和安全产生的影响,提出了一种含有分布式的主动配电网重构策略。以最小网损作为目标函数,将改进的教与学优化算法应用于主动配电网供电路径的快速优化中。通过算例对含分布式电源的主动配电网进行分析,以验证改进算法在配电网重构中的优越性。结果表明,该方法收敛速度快、寻优时间短、运行稳定。所做研究工作为我国配电网中接入分布式电源的优化方法提供了参考和借鉴。 |

Abstract: |
Given the increase of distributed power supply in the power distribution network, and considering the influence of its volatility and intermittent nature on grid stability and safety, this paper puts forward a reconfiguration strategy for an active distribution network with a distributed power supply. Taking the minimum network loss as the objective function, an improved teaching and learning optimization algorithm is applied for fast optimization of power supply paths in active distributed networks. The active distribution network with distributed power supply is analyzed using an example. It verifies the superiority of the improved algorithm in the reconstruction of the distribution network. The results show that the method has fast convergence, short optimization time and stable operation. The research provides a reference for the optimization of a distributed power supply connected to the distribution network in China.
