The balancing of generation and demand, known as Load Frequency Control (LFC) is a key challenge as always, and currently it requires further attention due to the intermittent Renewable Energies (RE) and new form of Loads, Electric Vehicles (EV) in the grid. An effort is put forward by proposing a model where these worrisome generation' sources and loads can be integrated in the grid, while exploring their strengths. Beside the Conventional Sources (CS), in this model EVs take part in the LFC and RE provides inertial response. The multi objective LFC problem, is synthesised as a robust mixed H₂/H_∞ based on static output feedback control problem addressed by iterative linear matrix inequality technique. As a test case, a three-area system having EVs, REs and CSs, is simulated in Matlab/Simulink. The EVs, which pose a challenge as an extra load, would be managed to avoid the need of too much new installation of CS and would help the integration of REs like wind and solar energy in the grid.
