An Optimal Allocation Method of Distributed PV and Energy Storage Considering Moderate Curtailment Measure

Increasing distributed generations (DGs) are integrated into the distribution network. The risk of not satisfying operation constraints caused by uncertainty renewable energy output is increasing. storage (ES) could stabilize fluctuation generation output. Therefore, it can promote consumption energy. A photovoltaic (PV) and ES optimal allocation method based on security region proposed. Firstly, a bi-level model PV established. outer layer nonlinear optimization model, taking maximum power supply benefit as objective function. inner day-ahead economic dispatching model. Then, quick solving steady-state An initial scheme determined with redundancy capacity. In addition, linear hyperplane coefficient used to convert one. Finally, proposed analyze improved IEEE 33-node system. It found that moderate curtailment measure peak have significant effect quota capacity DG exceeds sum load branch closely related cost technical parameters ES. Dynamic schemes should be formulated for
