The traditional power grid is unidirectional in its operation, where the power is transferred from generating facilities at far flung areas to the users in cities and villages. This system is serving us since few centuries. Lately, it has been suffering from several technical, economic, and environmental issues. Modern society requires this system to be more robust, scalable, and maintainable while also being cost effective, secure, and scalable. The distributed grid is expected to revolutionize power generation, transmission, and distribution by allowing two-way power flows for electrical power. The proposed system is a concept for building scalable distributed systems which consists of generating sources and storage elements with grid-connecting and working in island mode capabilities. This could allow renewable and green energy sources to become mainstream into a controlled utility and achieve higher utilization of existing energy infrastructure. MATLAB/Simulink software is used for simulation and implementation of the design which shows that this approach of controlling distribution of power is simple and effective. The MPPT algorithm used for maximizing power output from solar PV and a modified optimization algorithm which take different constraints for better flexibility is used for battery storage estimation. The operation is mainly focused on variable load scenarios and the response of the renewable generators to operate with variable generation and balancing it with stored energy for variable power demand.
