Grid Integrated Renewable Energy Network in Variety Sources

The technologies of hybridized alternative generator network are reliable enough to meet the load capacity of the urban and rural areas. This paper presents a designed microgrid network that will supply electricity to the community, storage and direct current loads. The renewable energy network comprises of a direct current (solar plant) generator operating as a primary direct current energy source in charging the storage systems (batteries and flywheel), supplying electric energy to the loads and sending the excess energy generated back to the grid network after the load capacity has been fully met. The hydro turbine, wind plant, and grid network (operating as the primary alternating current energy sources) and the biomass plant (operating as the secondary AC source) share a passable AC bus while the solar plant, flywheel and batteries share a passable DC bus. The microgrid network is highly flexible during energy exchange conversion flow between the alternating and direct current buses by a three-phase power electronic full wave bidirectional converter serving as an interface connecting the buses (AC/DC) together. A power flow operation where the grid network can supply electricity to the load/batteries/flywheel and receive excess electricity from the wind turbine, solar plant, biomass, and hydro turbine generators simultaneously after satisfying the load capacity. The batteries and flywheel receive and store energy from the AC/DC power sources and function as a backup energy supply towards the irregular, unstable wind turbine (AC) and solar plant (DC) generators (when they are experiencing capacity shortage). The flywheel function as a generator/motor to protect the batteries from damages and eliminate harmonics from the AC/DC variable power sources. The configuration from the microgrid network was analyzed by using diverse energy sources-flywheel-batteries power optimization software with hybrid dispatch controller system for the improvement of energy flow performance and storage management control, respectively.
