Abstract

The invention belongs to the renewable energy system field and relates to a renewable energy system simulation test and semi-physical simulation system. According to a solar cell array, an energy storage battery and a load in the renewable energy system simulation test and semi-physical simulation system, physical objects and simulators can replace each other, and the number and type of the physical objects of the assemblies can be adjustable, and therefore, a variety of work conditions can be simulated. The renewable energy system simulation test and semi-physical simulation system is not limited by weather and space. With the renewable energy system simulation test and semi-physical simulation system adopted, logical and performance testing of an energy manager can be facilitated; the energy flow process of a whole renewable energy system can be simulated; simulation testing can be performed on energy supply and demand balance performance of the energy system; and test and analysis conclusions can provide references for the design of the hardware of the energy manager.

Description

technical field [0001] The invention belongs to the field of renewable energy systems, and relates to a simulation test and semi-physical simulation system of a renewable energy system. Background technique [0002] A renewable energy system usually consists of a solar cell array, an energy storage battery, a load system, and an energy manager. When there is sunlight, the renewable energy system uses solar cells to convert light energy into electrical energy, thereby supplying power to the load. When there is no sunlight, the energy storage battery releases the stored electric energy to meet the power demand of the load; when the sunlight is weak, the solar battery and the energy storage battery jointly supply power to the load. Since the lighting conditions and load power requirements are dynamically changing, it is necessary to design an energy manager to reasonably control the conversion, storage and utilization of solar energy to achieve a balance between energy supply a...
