Abstract

En 中文
In this paper, a non-iterative sensitivity-based zsolve the distribution network reconfiguration (DNR) problem and ensure the security of the switch operation process, while maintaining the node voltage within the feasible range. The NSSE method involved the sensitivity-based network reconfiguration (SNR) stage and sensitivity-based power optimization (SPO) stage. In the SNR stage, the computational speed was improved by considering the dynamic voltage sensitivity with respect to the compensated power analysis, while the network power losses and number of switching times were minimized. The closed-loop and open-loop operation model was developed to solve the compensated power for simulating the switch operation process. Moreover, the maximum loop current was set as a constraint to avoid the equipment risk of switching operation. Each switch operation process can be formulated as integer quadratic programming (IQP) to obtain the optimal network topology and switch operation sequence with the non-iterative calculations. In the SPO stage, the active and reactive power outputs of distributed generations (DGs) were optimized to regulate the node voltage and reduce the active power curtailment. The effectiveness of the proposed NSSE method on the calculation speed and accuracy was validated in MATLAB.
