- Abstract:
- From the perspective of the total social cost，the overall framework of evaluation of power system plan-ning with large-scale wind farms was established. According to the annual chronological hourly data of wind power and load，for a given power system planning alternative，its system operation simulation was carried out，wherethe variability of wind power was considered. In the simulation process，daily-ahead(or week-ahead)unit commitment model，steady state and dynamic secutiy constraints based economic dispatch model and remedial control model were included. It was emphasized that based on the hyper-plane description of the bounary of the practical dynamic securityregion(PDSR)，the difficulty of dealing with stability constraints in the problem of solving for steady state and dy-namic secutiy constrained economic dispatch can be overcome easily. Hence the hourly fuel，environmental and net-work loss cost in the year for the given planning alternative could be calculated. These costs were to be combined with generation capacity cost，power network cost and system reliability cost，so that the total social cost of the alterna-tive could be determined. Therefore the evaluation of the total social cost of an alternative was achieved. Finally，the proposed method was validated by means of the case studied.
