TL;DR: The various Codes applicable to the University's electrical power system are mainly based upon a model of a single utility service, connected to a single premise, but the University’s electrical system consists of multiple utility services, a cogeneration facility, and a comprehensive primary distribution network connected to hundreds of premises.
Abstract: The various Codes applicable to the University's electrical power system are mainly based upon a model of a single utility service, connected to a single premise. The University’s electrical system, however, consists of multiple utility services, a cogeneration facility, and a comprehensive primary distribution network connected to hundreds of premises. Thus applying the codes to the University's electrical system is not straightforward as it would be in other locations.

TL;DR: In this paper, a directional control method for power flows on a set of interface lines between two regions of power system considering static voltage stability margin is developed, where a surface approximation approach is firstly used to obtain the relationship between the interface flow solution and the generation direction of generator (the portion of generation variation in each participating generator to satisfy the desired power increase on the interface and the system loss).
Abstract: A directional control method (DCM) for power flows on a set of interface lines between two regions of power system considering static voltage stability margin is developed in this paper. A surface approximation approach is firstly used to obtain the relationship between the interface flow solution and the generation direction of generator (the portion of generation variation in each participating generator to satisfy the desired power increase on the interface and the system loss). Then, an optimization model is built to determine the optimum dispatching scheme of generators. This method not only can control the total power on the interface to satisfy the power demand but also can realize the directional control of power on each interface line based on the needs of operation. The proposed DCM is further extended to determine the optimum dispatching scheme of generators for maximizing the interface flow margin (IFM), which is the active power margin of the key transmission lines between two regions of power system constrained by static voltage stability. A modified continuation power flow (MCPF) is used to show and evaluate the impacts of the DCM on the IFM. The New England 39-bus system and the IEEE 300-bus system have been employed to verify the effectiveness of the DCM.
