Today, the power system operation represents a challenge given the security and reliability
requirements. Mathematical models are used to represent and solve operational and planning issues
related with electric systems. Specifically, the AC optimal power flow (ACOPF) and the DC optimal
power flow (DCOPF) are tools used for operational and planning purposes. The DCOPF versions
correspond to lineal versions of the ACOPF. This is due to the fact that the power flow solution is
often hard to obtain with the ACOPF considering all constraints. However, the simplifications use
only active power without considering reactive power, voltage values and losses on transmission
lines, which are crucial factors for power system operation, potentially leading to inaccurate results.
This paper develops a detailed formulation for both DCOPF and ACOPF with multiple generation
sources to provide a 24-h dispatching in order to compare the differences between the solutions
with different scenarios under high penetration of wind power. The results indicate the DCOPF
inaccuracies with respect to the complete solution provided by the ACOPF
