Energy router topology device for source storage load optimal management and control method

Abstract

The invention discloses energy router topology and control for source storage load optimal management. The topology comprises an energy management and control center, an AC / DC converter, a first DC / DCconverter, a second DC / DC converter, a third DC / DC converter, a direct-current bus and four ports; the device is connected into a power distribution network with an alternating current load, the device is directly connected to a direct current output device, an energy storage battery and a direct current load of a distributed power supply such as a photovoltaic module or wind power, and maximum power control is carried out on the distributed power supply such as photovoltaic power generation or wind power, so that the grid-connected inverter link of the distributed power supply is omitted; energy storage charge-discharge control is carried out, and the difference between peak and valley is stabilized; when a power distribution network is out of order, automatic off-grid and grid-connectedswitching is carried out on the device, and power supply is carried out on the alternating current load; the energy management and control center is used for taking charge of the energy management ofeach port and is used for carrying out power control on each port, so that optimal router management of source storage load energy sources is realized. The energy management and control center is used for receiving a dispatching command of a superior power distribution network, and the power of the energy router to the power distribution network is controlled so as to meet the dispatching requirement. The energy router topology has significant practical application values.

Description

technical field [0001] The invention relates to an energy router, in particular to an energy router topology device and control method for optimal management of source, storage and load. Background technique [0002] With the advancement of electricity reform and marketization, future electricity trading will become more and more free and flexible. As new energy generation penetrates into power distribution terminals, end users in the past can switch between loads and sources, power system power distribution will gradually change from the current "one-to-many" structure to "many-to-many" form, and each The terminal can be switched arbitrarily between the buyer and the seller, and the diversification of electric energy flow is greatly increased. In order to accurately dispatch electric energy in a quantitative, fixed-point, and timing manner, each terminal and node of the power grid needs to realize active energy dispatch management and realize accurate and controllable ener...
