Abstract: This paper proposes a new energy strategy to distribute energy at each bus in Viet Nam electric power system with the participation of photovoltaic and wind power generations. A structure for this system is also constructed including some main blocks: power circuit, forecasting center and center of measurement, dispatch and control. Each block closely works together with others and energy storage to have a balance power at any time in whole considered cycle. A demand-side management algorithm is designed corresponding to a case study that has energy from the generations smaller than consumed energy of electric load in whole time stages. In this algorithm, the deficient energy in stages having high and medium electric price levels can be bought from the electric power system to charge to the energy storage in the stage having low electric price level to reduce the economic function. Simulation results were carried out by the MATLAB 2017a software to show the feasibility of the demand-side management program to re-dispatch power flows in whole system and bring out high economic effectiveness.
