Abstract

The invention provides an energy control system and method for a hybrid power supply system of a communication base station. The energy control system comprises a power grid, a diesel generator, a photovoltaic system, a lithium battery, a lead-acid battery and a main controller. The power grid and the diesel generator are connected with an AC/DC rectifier through an automatic change-over switch, and the AC/DC rectifier is connected to a system DC busbar. The diesel generator is connected with a system direct-current busbar through the DC/DC converter; the photovoltaic system is connected withthe system direct-current busbar through a MPPT controller; the lithium battery and the lead-acid battery are connected with the system direct-current busbar through a direct-current power flow distributor; the system direct-current busbar is connected with a load and used for supplying power to the load; and the main controller is used for realizing the overall operation control of the system andadjusting the output power of the lithium battery, the lead-acid battery and the diesel generator. According to the invention, the operation of the diesel engine can be reduced, the lithium battery is efficiently used, the residual electric quantity of the lead-acid battery is extracted, and power supply reliability is improved.

Description

technical field [0001] The application belongs to the technical field of energy management, and in particular relates to an energy control system and control method for a communication base station hybrid power supply system. Background technique [0002] In recent years, grid-connected or island-type hybrid power supply systems for base stations have been frequently deployed around the world due to their flexible design and low cost. The primary task of system design is to optimize and design the operation strategy of the system under the condition of considering the grid power supply situation and equipment operation constraints, minimize the daily load operation cost, and maintain the reliable power supply of the load throughout the day. In order to enhance the reliability of base station load power consumption and reduce carbon dioxide emissions, more and more energy forms have been added to the base station power supply system, such as photovoltaics, wind power, diesel ...
