Reactive Power Control to Alleviate Bus Voltage Violations in an AC-DC System

摘要: This paper presents a number of refinements to the formulation as well solution procedure for coordinated reactive power control scheme using conventional sources, transformer tap, and also DC converters multiterminal network. The proposed approach offers considerable improvements in computational efficiency. These can be attributed (a) reduction dimensionality by exploiting decoupled nature real flows AC network, (b) sparse matrix techniques selectively generate required sensitivity relationships opposed computing entire matrix, (c) an efficient dual simplex LP adapted solve desired controls. Numerical examples are presented demonstrate effectiveness new show that even small 30 bus, 5 terminal system significant time obtained.
