چکیده
The volatile and intermittent nature of distributed generators (DGs) in active distribution networks (ADNs) increases the uncertainty operating states. introduction phasor measurement units (D-PMUs) enhances monitoring level. trade-offs computational performance robustness state estimation network states are great significance for ADNs with D-PMUs DGs. This paper proposes a second-order cone programming (SOCP) based robust (RSE) method considering multi-source measurements. Firstly, linearized model related to SOCP variables is formulated. phase angle measurements converted equivalent power Then, revised SOCP-based RSE weighted least absolute value estimator proposed enhance convergence bad data identification. Multi-time slots D-PMU utilized improve accuracy RSE. Finally, effectiveness illustrated modified IEEE 33-node 123-node systems.
