Energy router topology and control method for unified management of source, storage and load

Abstract

The invention provides a source-storage-load unified management energy router topological structure and a control method thereof. The energy router topological structure comprises an energy managementand control center, an AC/DC converter, a first DC/DC converter, a second DC/DC converter, a DC/AC converter, a third DC/DC converter, a DC bus and five ports. The device is connected with the AC load and the DC load and directly connected with the DC output voltage of a photovoltaic component or wind power or other distributed power supplies, the grid-connected inverter of the distributed powersupplies is eliminated, and the energy management and control center is responsible for energy management of all the ports and power control of all the ports so that unified router management of the source-storage-load energy can be realized. The energy management and control center receives the scheduling instruction of the upper power grid to control the power outputted to the power distributionnetwork by the energy router to meet the scheduling requirement.

Description

technical field [0001] The invention relates to an energy router, in particular to a topology structure and a control method of a multifunctional energy router. 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 power 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 every Each 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 quantitatively, at fixed points, and at regular intervals, each terminal and node of the power grid needs to realize active energy dispatch management and accurate control of energy flow. However, tradi...
