Comprehensive unified power flow controller ( UPFC ) technology can calculate voltage control parameters of UPFC, but it increases the nonlinearity Newton calculation. When comprehensive is combined with intelligent algorithm, only be optimized through active and reactive on branch, which makes optimization convergence worse. Therefore, an optimal calculation method for distribution network bas...

A robust defensive strategy for active distribution networks considering multi-uncertainties and island restoration is studied. Firstly, the authors take triple uncertainties into consideration, that is, attack strategy, amount of wind power generation solar irradiation. Next, a trilevel defender-attacker-defender (DAD) two-stage mathematical model established to make full use energy storage su...

Utility-scale and small scale wind solar power installations along with electric vehicle charging stations, other active sources of energy are increasing at the medium lower voltage levels in distribution grid. This situation requires a better understanding impact high penetration weather-dependent renewable on operating conditions network both low levels. Despite need, multi-voltage level mode...

Active distribution network planning is of importance for utility companies in terms distributed generation investment, reliability assessment, optimal reactive power planning, substation evaluation, and feeder reconfiguration. However, it challenging current model-based optimization problems to guarantee the performances active due an empirically pre-defined solution space. To overcome this is...

This paper deals with the derivation of dynamic equivalents active distribution networks, hosting inverter-based generators as well static and motor loads. Equivalents are reduced-order models for use in simulations transmission system. They grey-box types their parameters identified from large-disturbance Monte-Carlo accounting model uncertainty. After presenting an overview identification met...
