【摘要】：在传统Newton-Raphson潮流算法中一般仅定义平衡节点、有功功率—电压节点、有功功率—无功功率节点这三类节点,难以直接使用传统Newton-Raphson潮流算法求解含下垂控制策略的微电网潮流问题。提出一种类奔德斯分解的潮流计算新方法,将采用下垂控制策略的孤岛微电网的潮流计算问题分解成传统Newton-Raphson潮流计算子问题和下垂节点更新子问题,通过两个子问题的交替迭代获取潮流解。该方法将一个复杂的原问题分解成了两个简单的子问题,实现了原问题的高效、快速求解。通过算例分析,验证了所提方法的可行性和有效性。
[Abstract]:In the traditional Newton-Raphson power flow algorithm, only three kinds of nodes are defined: balance node, active power voltage node, active power and reactive power node. It is difficult to directly use traditional Newton-Raphson power flow algorithm to solve the power flow problem of microgrid with droop control strategy.A new power flow calculation method based on Bendes decomposition is proposed. The power flow calculation problem of isolated island microgrid using droop control strategy is decomposed into traditional Newton-Raphson power flow calculation sub-problem and droop node update sub-problem.The power flow solution is obtained by alternating iteration of two subproblems.This method decomposes a complex original problem into two simple sub-problems and realizes the efficient and fast solution of the original problem.The feasibility and effectiveness of the proposed method are verified by an example.
