Problems solved by technology

[0004] However, most of the existing control methods for optical storage and diesel micro-grid systems are set for newly-built optical storage and diesel micro-grid systems, which are not suitable for optical storage and diesel-diesel micro-grid systems that include relatively old diesel engine power generation systems. The stability of the microgrid system is not good

Abstract

The invention provides an optical storage firewood microgrid system and a control method thereof, wherein the system and the method are applied to the technical field of new-energy power supply. According to the method, a diesel generator system is controlled to operate independently to supply power and output load demand power; when it is judged that an optical storage system meets a switch-in condition, the optical storage system is controlled to switch in and output first shared power, and the diesel generator system is controlled to output second shared power; and when it is judged that the optical storage system meets the a switch-out condition, the diesel generator system is controlled again to independently operate to supply power and output load required power, and the optical storage system is controlled to switch out. According to the method, the first shared power is obtained based on the preset sharing proportion and the load demand power, the optical storage system can replace a fixed number of diesel generators, the method is suitable for the light storage diesel microgrid system comprising an old diesel engine power generation system, and the stability of the opticalstorage diesel microgrid system is improved.

Description

technical field [0001] The invention relates to the technical field of new energy power supply, in particular to an optical storage and firewood microgrid system and a control method thereof. Background technique [0002] Today, with the increasing development of power grid technology and power supply conditions, there are still some Southeast Asian countries (such as Indonesia, Maldives, etc.), domestic island areas and remote mountainous areas without power areas that cannot be covered by the power grid. The power consumption in these areas generally relies on diesel generators to solve. If the scale of the non-electric area is large, multiple large diesel generators need to be connected in parallel to form a large off-grid power supply system to supply power for the area. [0003] As we all know, the power supply system composed of diesel generators has a series of problems such as noise, pollution and high cost. With the advancement of photovoltaic power generation and...
