In this paper, a new method for reference network considering network topology optimization is proposed. The actual operation mode optimization and the correction control with transmission switching under the contingency situation are taken into account in the proposed method. Based on the forecasted load values of each period in predictive multi-time scale and candidate transmission line schemes...
With the diversified development of electrical loads, and the large-scale integration of volatile renewable generations, power system operation, control and planning face the challenge of increasing injection uncertainties. In this paper, a new method for reference network considering nodal injection uncertainties is proposed. The actual operation mode optimization and reserve configuration of power...
For the randomness and asynchronous characteristics of wind power and photovoltaic (PV) generation, large-scale integration of renewable generations into power grid, especially when the electric network topology is fixed, has brought the problems of transmission congestion and voltage security in power system operation. In order to make better use of existing network to promote security and economy...
Static thermal rating method converts the thermal constraint which represents the heat capacity of conductor into electric constraints, using static heat balance equation (HBE). It ignores the phenomenon of thermal inertia, and as a result, it limits the full exertion of line heat capacity, to some extent. Considering the asynchronous characteristic between electricity and heat, the definition of...
If the reactive power (var) supply capability is not constrained; the transmission line loadability may be limited by the angle or thermal static stability. Once the reactive power supply is limited or not great enough to support the operation, the transmission line loadability will be limited by voltage. The reactive power supply capability has great influence on the transmission line loadability...
