The document presents a control strategy for managing power flow in a DC microgrid integrating solar and wind energy sources. It discusses the necessity of a power flow algorithm to balance energy supply from various sources to meet load demands efficiently, validated through simulations in MATLAB/Simulink. The results demonstrate the algorithm's effectiveness under varying load conditions and fluctuations in renewable energy output.

CONCLUSION:
A Management of power flow and control algorithm for DC microgrid with solar and wind
energy sources is presented. As the system involves different intermitted energy sources and load
whose demand can vary, it is necessary to develop a Management of power flow and control
algorithm for the DC Microgrid. To provide ceaseless power supply to the loads and balance the
power flow among the different sources at any time, a Management of power flow algorithm is
developed. The feasibility of the algorithm has been tested for various load conditions and for
changes in solar and wind power.

As different energy sources like solar, wind, fuel cell, and diesel generators can be integrated into the DC grid, Management of power flow among the sources is essential. In this paper, a control strategy for Management of power flow in DC micro grid with solar and wind energy sources is presented. As the regulation of voltage profile is important in a standalone system, a dedicated converter is to be employed for maintaining the DC link voltage. DC link voltage is regulated by the battery circuit while maximum power is extracted from Solar and Wind to feed the loads connected at the DC bus. A power flow algorithm is developed to control among three sources in the DC Microgrid. The algorithm is tested for various load conditions and for fluctuations in solar and wind power in MATLAB/SIMULINK environment. KEYWORDS: 1. DC microgrid 2. Power flow administration 3.
