Abstract

Maintenance of system frequency within utility prescribed tolerance band was considered as exclusive responsibility of conventional power plants. Fluctuating power due to varying nature of wind inflict extra power imbalance to the power system leading to frequency deviation from the nominal value. This power generation needs to be balanced with other fast controllable generation sources. With increasing share of wind based energy generation on utility grid, provision of ancillary services from them is also gaining the status of necessity for total system reliability. Frequency regulation makes up as one of the category of these ancillary services for power system security management and quality reliability. Automatic generation control (AGC) is an important function for load frequency control (LFC). This paper addresses design aspects of LFC scheme for minimization of system frequency of interconnected multigeneration power systems in the presence of wind power. Integral of time multiplied by absolute errors (ITAE) has been applied to determine the optimal values for the controller gains of the system. It has been observed from simulations that control area having wind integrated with base load plant gives better AGC performance than the control area having wind integrated with peak load plant.
