柔性配电网氢储能SOP长-短周期协调低碳运行优化方法OA

In response to the rapid source-load power fluctuations and seasonal energy imbalances caused by the high penetration of renewable energy and new types of loads in distribution networks,a long-short cycle coordinated optimi-zation method for flexible distribution networks using hydrogen energy storage integrated soft open points(HSOPs)is proposed.A low-carbon operation optimization model of flexible distribution networks with HSOPs considering source-load matching is established,in which the converter losses of HSOPs and energy losses of the hydrogen energy storage system are taken into account to characterize the temporal operation characteristics of HSOPs in detail.A rolling optimi-zation method based on bi-level model predictive control is employed to solve the established model,so that a real-time updated long-short cycle coordinated optimization strategy for flexible distribution networks is obtained.The effective-ness of the proposed method is validated on a modified IEEE 33-node test example,and results demonstrate that this method can effectively improve the long-term source-load matching of flexible distribution networks under scenarios with uncertain sources and loads,enhance the local consumption of photovoltaic power and reduce the carbon emissions from distribution networks.
