Embodiment Construction

[0021] The present invention is further described below with reference to the accompanying drawings and specific embodiments.

[0022] figure 1 It is shown that the main application object of the present invention is a distributed energy system with a micro gas turbine as the core. The system includes a renewable energy power generation device RE, a micro gas turbine cogeneration unit MTCG, a gas boiler GB, an electricity storage device ES, a storage Heat device HS, heat exchanger HE, electric water heater EH, etc. The distributed energy system is connected to the external power grid and can realize cogeneration of heat and power. Micro gas turbines are thermoelectric coupling devices, and the selection of micro gas turbines is the key to the planning and design of distributed energy systems.

[0023] The invention relates to a unit selection method for a micro gas turbine combined heat and power system. The selection method includes the steps of load processing, micro gas t...

Abstract

Provided is a unit type selection method of a micro gas turbine combined heat and power system. The types and set numbers of micro gas turbines are selected reasonably according to different usage occasions, different heating loads, electrical load characteristics and system operation control requirements of the combined heat and power system, the utilization efficiency of fossil energy is improved, and the annual cash flow of the system is made to be minimum. According to the unit type selection method of the micro gas turbine combined heat and power system, the types and the set numbers of the units in the micro gas turbine combined heat and power system can be selected conveniently and optimally, and the planning and designing level of the micro gas turbine combined heat and power system is improved.

Description

technical field [0001] The invention relates to a type selection method for a unit, in particular to a type selection method for a micro gas turbine combined heat and power supply system. Background technique [0002] Due to its flexible variable load operation, low initial investment, good power supply reliability, small transmission loss, and its ability to absorb and absorb renewable energy, distributed energy systems are gaining more and more attention in the world energy field. more attention. However, as the core of the distributed energy system, the selection method of cogeneration equipment mostly relies on engineering experience, and it is often not scientific and reasonable enough to be obtained by comparing various alternatives, resulting in waste in actual operation. [0003] With the continuous progress of power electronics technology, information technology and Internet technology, some scholars have proposed the concept of microgrid. Microgrid is a system co...
