In the energy management of the isolated operation of small power system, the economic scheduling of the generation units is a crucial problem. Applying right timing can maximize the performance of the supply. The optimal operation of a wind turbine, a solar unit, a fuel cell and a storage battery is searched by a mixed-integer linear programming implemented in GAMS (general algebraic modeling systems). A VPP (virtual power producer) can optimal operate the generation units, assured the good functioning of equipment, including the maintenance, operation cost and the generation measurement and control. A central control at system allows a VPP to manage the optimal generation and their load control. The application of methodology to a real case study in Budapest Techpsilas, demonstrate the effectiveness of a this method to solve the optimal isolated dispatch of the DC microgrid renewable energy park. The problem has been converged in 0.09 seconds and 30 iterations.
