Robust UC model based on multi‐band uncertainty set considering the temporal correlation of wind/load prediction errors

Reliability-Constrained AC Power Flow-Based Co-Optimization Planning of Generation and Transmission Systems With Uncertainties

“…It is recognized by researchers that the coordinated optimization of generation and transmission system would achieve a more reliable and economical solution [5]- [8]. In addition, various challenges brought by uncertainties of power generation, load and transmission line could be addressed well via robust optimization [9]- [10]. To further include the spatiotemporal correlation of uncertainty prediction error, a linear polyhedral uncertain set in introduced in references [11]- [12].…”

“…Power system uncertainties are not considered in these cases for the sake of comparison. In Case 1, only four assets are invested over the five-year horizon, where candidate units G1 and G3, and candidate transmission lines L3 and L11 are constructed with a total cost of $1.3704×10 9 . However, overloads and under voltage issues happen in the system, which may require addition investment in generating units, transmission lines and reactive compensation.…”

“…Moreover, it could also be observed in Table I that the investments of some important assets are earlier, like generating units G1 and G3. As a result, the total cost increases to $1.3949×10 9 . When CBs and SVCs are considered in Case 3, the total cost is reduced by $8×10 5 .…”

“…As a result, the investment of transmission line L3 is delayed while investment of transmission line L11 is avoided. In this case, the total cost increases to $1.3941×10 9 . Table II shows the annual LOLE criterion of Cases 1-4.…”

A Game Theoretical Pricing Mechanism for Multi-Microgrid Energy Trading Considering Electric Vehicles Uncertainty

“…At present, many literatures research on PV and WT generation uncertainty. The weather forecast is used as the method to analyze the power generation uncertainty of PV and WT [12] [28]. With a large number of EVs( such as EV fleets) connected to microgrid for charging, more literatures have been focused on the random characteristics caused by the uncertainty of EV's plug-in time and initial SOC which are the issues affect players' roles in the twolevel Stackelberg game model.…”
