Abstract:

The authors summarize papers that were presented at a panel session sponsored by working group 15.05.08 on DC economics and operating strategies. Typical cost figures are provided for line and terminal equipment. There are detailed discussions and extensive references on many other factors that are usually included in such comparisons. The reliability and capacity comparisons between AC and DC alternatives are discussed regarding a case study done by Ontario Hydro. The conversion of an AC power corridor to DC to increase the power-transfer capability is of increasing interest because new transmission corridors are very difficult to obtain. The economic perspective on the conversion of a power corridor is treated in some detail. Power-transfer capacity can also be increased by adding series and shunt compensation as discussed. The impact of each alternative on the interconnected power-system reliability and security is considered. System dynamic performance considerations showed how one experienced planner compared the assumed performance of an existing HVDC transmission system with an assumed AC alternative in response to some specific contingencies and specific system conditions.<>
