ABSTRACT:
Optimization and placement of spinning reserve is an
important issue in power system planning and operation. Systematic way for
security assessment of operating reserve needs to study. A security assessment
index system for operating reserve in large interconnected power grids is presented
in this paper. Firstly, classification and determination methods of operating
reserve at home and abroad are investigated, and operating reserve is divided
into transient state operating reserve and quasi-steady state operating reserve
from the view of security assessment. Secondly, assessment indexes and optimization
methods for transient state operating reserve are studied. Thirdly, optimization
model, deterministic and probabilistic optimization methods for quasi-steady
state operating reserve are explored. Finally, some principles for
determination of operating reserve are suggested, and a security assessment
index system is put forward. The proposed index system, considering both
transient and quasi-steady state, both deterministic and probabilistic methods,
provides a systematic way to assessment and arrangement of operating reserve.
