摘要

The solution of voltage violations in each hourly scenario of the Spanish electricity market must consider: (a) the connection of off-line units (considering the active and reactive power injection effect); (b) the adjustment of the voltage control resources (generator voltages, transformer taps and shunt reactors and capacitors) and (c) the preventive solution of the voltage violations under the occurrence of the postulated contingencies. This is the second part of a two-part paper. Part Ⅰ has analyzed the complexity of eliminating voltage violations proposing a simple methodology that includes the following steps: (a) contingency analysis, (b) decoupled solution of voltage violations for each hourly scenario and (c) daily-coupled solution of voltage violations. In addition, Part Ⅰ has described the mathematical formulation of a set of mixed-integer optimization algorithms designed to obtain the hourly decoupled solution and the daily-coupled solution of voltage violations in the Spanish electricity market. In Part Ⅱ, the methodology and performance of the algorithms will be illustrated and compared using an actual example of the Spanish electricity. The hourly solution of the algorithms is compared from an economic and technical point of view and the system cost reduction of the daily solution is demonstrated.
