An Inertia Reserve Capacity Planning Method for Power Systems Considering Risk Preference

IEEE Access
The traditional reserve planning method implicitly includes inertia in the frequency response reserve without realizing separate and accurate planning for inertia reserve, and cannot consider the risk preference of the decision maker, which leads to the ...
