基于双向搜索算法的用户停电损失估算模型

Customer interruption cost estimation model based on bidirectional search algorithm

准确且快速地估算用户停电损失对配电网优化、规划具有重要作用.提出一种基于双向搜索算法的用户停电损失估算模型,通过编程形式将双向搜索算法与用户停电损失估算模型相结合,首先把断路器的故障率考虑到双向搜索算法中,从而更加接近真实情况;然后计算每个负荷点的平均故障率和平均故障持续时间,将平均故障率和平均故障持续时间代入用户停电损失模型中,求得每个负荷点的用户停电损失;最后把所有负荷点的用户停电损失相加得到总用户停电损失.以IEEE-RBTS BUS 6中的馈线F4为例验证了模型的有效性.

Accurate and fast estimation of customer interruption cost plays an important role in distribution network optimization and planning.A customer interruption cost estimation model based on bidirectional search algorithm was proposed,the bidirectional search algorithm was combined with the customer interruption cost estimation model through programming.Firstly,the fault rate of the circuit breaker was taken into account in the bidirectional search algorithm,so as to be closer to the real situation;then the average failure rate and average duration of failure of each load point were calculated,the average failure rate and average duration of failure were substituted into the customer interruption cost model,the customer outage loss of each load point was obtained;finally,the total customer interruption cost was obtained by adding the customer outage losses at all load points.Taking feeder F4 in IEEE-RBTS BUS 6 as an example,the effectiveness of the model was verified.
