An innovative pluralistic Load-Frequency Control scheme for the power flow control along corridors on the Italian border

The need to realize LFC control schemes which consider the conditions imposed by the electricity market and which allow the preventive and corrective resolution of power flow overloads leads to the analysis of new solutions which increase the effectiveness and the flexibility of the relevant control functions. The classical centralized LFC controller regulates the power exchanges through the border and the frequency at predefined values, but it does not allow to solve possible overflows on single lines or on defined sections. This paper is aimed at describing an innovative LFC control scheme based on virtual control areas. Its goal is to limit the power flows on adequate sections below a predefined value. As an application example, the situation on the Italian border is presented and commented
