Please refer to Fig. 2, Fig. 2 is the schematic diagram of renewable energy resources electric power system of the present invention.Renewable energy resources electric power system 2 of the present invention mainly comprises: energy source regeneration apparatus 20, energy storage device 21, bus module 22, the first DC-DC module 231, the second DC-DC module 232, the 3rd DC-DC module 233, DC/AC module 24, handover module 25, electrical network 26 and power consumption equipment 27.Energy source regeneration apparatus 20, energy storage device 21, electrical network 26 have respectively link a, b, c, d with power consumption equipment 27.
Energy source regeneration apparatus 20 is by link a electric property coupling the first DC-DC module 231.The first DC-DC module 231 is electrically coupled to bus module 22.Energy storage device 21 is by link b electric property coupling the second DC-DC module 232 and the 3rd DC-DC module 233.The second DC-DC module 232 and the 3rd DC-DC module 233 be electric property coupling bus module 22 respectively.DC/AC module 24 electric property coupling bus modules 22 and handover module 25.Electrical network 26 is by link c electric property coupling handover module 25.Power consumption equipment 27 is by link d electric property coupling handover module 25.
In the present invention, energy source regeneration apparatus 20 mainly is introduced as an example of solar energy equipment example, but therefore the present invention does not limit.The first DC-DC module 231 is generally boost module, and when energy source regeneration apparatus 20 is solar energy equipment, the first DC-DC module 231 main functions that realize maximum power tracing (MPPT).Yet the DC source voltage that produces at solar energy equipment can be realized maximum power tracing by means of the control of DC/AC module 24 or the second DC-DC module 232 during greater than the voltage of bus module 22.In such application, can not need the first DC-DC module 231 or the first DC-DC module 231 inoperative when this operating state.
The key link that bus module 22 connects for each side's energy, and the voltage of bus module 22 is relatively stable.What the first DC-DC module 231 can produce energy source regeneration apparatus 20 can be sent to bus module 22, and bus module 22 can absorb the energy of energy storage device 21 or provide energy to energy storage device 21 by the second DC-DC module 232 or the 3rd DC-DC module 233.Bus module 22 can be by DC/AC module 24 from electrical network 26 absorbed energies or provide energy to electrical network 26.Bus module 22 also can provide energy to power consumption equipment 27 by DC/AC module 24.So, having reduced in solar powered (or other renewable energy resources power supplies) situation will be first the link (unnecessary intermediate link) of chemical energy with Conversion of Energy, improved thus the utilization ratio of solar energy (or other renewable energy resources), realized simultaneously energy flow under the different application condition to flexible control.
According to above-mentioned, bus module 22 is the hinge of energy flow, and can be monobus module or dual bus module.Each module of structure for different bus module 22 can have corresponding different topology.For example: when adopting the monobus module, DC/AC module 24 can be used full-bridge inverter, and when adopting the dual bus module, DC/AC module 24 can be used half-bridge inverter.
The second DC-DC module 232 and the 3rd DC-DC module 233 main realizations discharging and recharging energy storage device 21.For non-isolation applications (being that energy storage device 21 and bus module 22 be not through isolation), the second DC-DC module 232 and the 3rd DC-DC module 233 can be integrated into the circuit of an energy in bidirectional flow, and this moment can be only with a direct current charge-discharge modules.Yet, use for isolated form, usually with two DC-DC modules: the second DC-DC module 232 is charging DC-DC module, be used for to energy storage device 21 chargings, the 3rd DC-DC module 233 is discharge DC-DC module, is used for the energy of energy storage device 21 is provided to bus module 22.Energy storage device 21 is secondary cell normally, for example: lithium battery, Ni-MH battery or nickel-cadmium cell.
