摘要
针对传统系统恢复中路径选择方法对直流恢复限制严重的问题,提出含直流落点受端系统恢复方法。对直流输电在系统恢复中的特性进行分析,综合考虑系统恢复效率和恢复过程中的系统安全性,以恢复期间总发、输电量与网架充电无功的比值作为优化目标,建立考虑并联线路的系统恢复模型;然后综合考虑直流启动及系统运行等约束,结合混合粒子群算法进行系统恢复方案的求解。以IEEE 39节点算例和中国西南某地区实际电网算例验证了所提出方法的有效性。
The path optimization method proposed in previous studies severely restricts the restoration of LCC-HVDC system. To overcome this weakness, this paper studies power system restoration with AC/DC conversion terminal at the receiving-end. In this paper, the characteristics of LCC-HVDC transmission systems under the condition of system restoration are analyzed. To ensure the efficiency and security of restoration, the system restoration optimization model considering parallel transmission lines is established by taking the ratio of total power generation and grid charging reactive power as the optimization goal. Then hybrid particle swarm optimization is adopted to solve the problem of power system restoration, which is characterized by various constraints. The effectiveness of the proposed method is demonstrated and validated by the optimization results on the modified IEEE 39-bus system and a practical power system in Southwest China.
