交直流混合微电网是实现分布式能源并网的有效手段。并网运行的微电网应准确、快速地追踪配电网关于公共连接点的调度指令。常见追踪方法存在计算耗时较长和易受模型与控制误差干扰等问题,追踪效果有时欠佳。为此
提出了基于量测反馈的分布式追踪方法:在模型层面
考虑了交流侧三相不平衡、交直流侧功率耦合和网络安全约束;在方法层面,通过非迭代计算模式得到了分布式能源输出功率设定值,提高了追踪的快速性,同时引入量测反馈降低了模型误差和非迭代计算模式带来的误差影响,提升了追踪精度。仿真表明,通过所提方法,即使在一定的通信时延和分布式能源出力波动的干扰下,交直流混合微电网依然可以准确、快速地追踪配电网调度指令,并保证自身运行安全。所提方法有助于微电网参与电网调度。
A hybrid AC/DC microgrid is an effective way to achieve the integration of distributed energy resources. A grid-connected microgrid should accurately and rapidly track the dispatching instructions of the distribution system on the point of common coupling. The traditional tracking methods have the problems such as relatively long calculation time and easy to be disturbed by model and control errors
which sometimes lead to poor tracking effects. Therefore
a distributed tracking method based on measurement feedback is proposed. At the model level
the three-phase imbalance on the AC side
the power coupling between AC and DC sides
and the network security constraints are considered. At the method level
the setpoints of the output power for distributed energy resources are obtained through a non-iterative calculation mode which improves the rapidity of tracking. And the errors caused by the model and the non-iterative calculation mode are reduced by applying the measurement feedback which improves the tracking accuracy. Simulations demonstrate that even under the disturbance of certain communication delays and distributed energy resource output fluctuations
the hybrid AC/DC microgrid can still track the dispatching instructions of the distribution system accurately and fast
and ensure the safe operation of itself by the proposed method. The proposed method is helpful for the microgrid to participate in power grid dispatching.
