Embodiment Construction
[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0031] refer to figure 1 , an independent microgrid operation control method composed of energy storage and micro gas turbines, comprising the following steps:
[0032] S1. Data collection: Microgrid system data collection includes energy storage system power data, battery status data, and micro gas turbine outlet power data;
[0033] S2. The control system of the energy storage system: the energy storage system is controlled by PLC, which is only used to adjust the frequency of the microgrid, that is, to obtain the frequency value of the power bus bar collected by the frequency transmitter, and calculate the energy storage according to the deviation between the real...

The invention belongs to the field of power systems, particularly relates to an operation control method for an independent micro-grid composed of energy storage and a micro gas turbine, and provides the following scheme aiming at the problems that the existing domestic micro gas turbine technology is not mature enough, many control capabilities are not complete, and other functions except the basic power generation capability basically do not have. The method comprises the following steps: S1, data collection: micro-grid system data collection comprises energy storage system power data, battery state data and micro gas turbine outgoing line power data; S2, control system of an energy storage system: the energy storage system is controlled by a PLC and is only used for adjusting the frequency of the micro-grid, the selection range of a power source in the micro-grid is expanded, the domestic micro gas turbine has the market space of participating in the isolated grid type micro-grid, the response time of the micro-grid is extremely short, and the power source reliability during isolated grid operation is greatly improved; The remote control capability is realized, and the automation degree is high.
Description
technical field [0001] The invention relates to the technical field of power systems, in particular to an operation control method for an independent microgrid composed of energy storage and a microgas turbine. Background technique [0002] In the context of carbon peaking and carbon neutrality, the use of low-carbon energy is a trend in the development of human society, and natural gas instead of diesel power generation is a specific measure. It is an emerging solution to use gas turbines for power supply in the field where temporary power consumption or high power supply reliability is required. For a long time, the gas turbine market and technology have been dominated by a small number of European, American and Japanese companies. The domestic gas turbine technology is immature, and many automatic control and other conventional control functions of generator sets are not available. [0003] Judging from the current research on micro-grid stable operation control technolo...
