Embodiment 1

[0040] A monitoring system for a DC microgrid system disclosed in this embodiment, the control object is a DC microgrid system 1, and the DC microgrid system 1 includes a power supply module, a load module, an energy storage module, a grid-connected controller, The DC microgrid system is connected to the power circuit 101 and the DC microgrid system communication bus 102 . The monitoring system 2 includes a local monitoring module, an information processing module, a strategy optimization module, a data storage module, an information exchange module, and a remote monitoring module. In this example, the power module selects photovoltaic power generation equipment, and the load module includes adjustable loads and non-adjustable loads. A non-adjustable load is a load that cannot change the usage time, such as a lamp at night; an adjustable load is a load that can change the usage time, such as a washing machine. The energy storage module selects a lithium-ion battery and a bidi...

Abstract

The invention discloses a monitoring system and a monitoring method used for a direct-current microgrid system, and belongs to the monitoring and management fields of electric power system direct-current microgrid systems. In the monitoring system disclosed by the invention, the direct-current microgrid system is a controlled member, and the direct-current microgrid system comprises a power module, a load module, an energy storage module, a grid-connected controller, a direct-current microgrid connecting power circuit and a direct-current microgrid communication bus. The monitoring system comprises a local monitoring module, an information processing module, a strategy optimizing module, a data storage module, an information exchange module and a remote monitoring module. The invention also discloses a monitoring method of the monitoring system used for the direct-current microgrid system. The technical problem to be solved by the invention is to realize intelligent control for the direct-current microgrid system through a remote terminal, so that the equipment operation condition of the direct-current microgrid system is effectively monitored, and the equipment exception condition of the direct-current microgrid system is known and processed in time.

Description

technical field [0001] The invention belongs to the field of monitoring and management of a direct current microgrid system in a power system, and in particular relates to a monitoring system and a monitoring method for a direct current microgrid system. Background technique [0002] With the rapid development of the global economy, the demand for electric energy in all walks of life is increasing, but the amount of fossil fuels is decreasing day by day, and the development of renewable energy is imminent. Embedding renewable energy as a power source in a microgrid is distributed generation. The construction of distributed power generation has the characteristics of flexibility and decentralization. Using distributed power generation can make full use of existing power grid facilities and greatly reduce the cost of power grid construction. Combining distributed generation with energy storage, load and power electronic devices to form a microgrid can provide high-quality ele...
