Embodiment

[0040] The present invention proposes an energy management method for a microgrid system with controllable heat load based on classified management, and proposes a microgrid operation cost function as follows:

[0041] F(k+1)=P g (k+1)·c g +|T(k+1)-T h |·c T +|SOC(k+1)-SOC h |·c SOC +|P g (k+1)|·c v

[0042] In order to simplify the energy management process, the energy management control instructions are divided into the following two categories:

[0043] 1) Thermal load control command: only control the thermal load power of the microgrid without changing the energy storage power. At this time, the power expression is as follows:

[0044]

[0045] 2) Electric energy storage control command: only control the electric energy storage power of the microgrid, and do not change the thermal load power. At this time, the power expression is as follows:

[0046]

[0047] In each control cycle, the power values ​​of the two control commands and the operating cost F(k+1) u...

Abstract

The invention discloses an energy management method for a micro grid system with electrical and thermal loads, which includes the following steps: S1, a comprehensive model of a micro grid system withcontrollable thermal loads is established, and a cost function F(k+1) is put forward to measure the operation cost of each control cycle, wherein the cost function includes the electricity cost of the micro grid, the grid-connection power, the indoor temperature and the state of charge of an electric energy storage system, and the smaller the value of the cost function is, the better the operation effect of the micro grid is; and S2, micro grid energy management instructions are divided into load control and energy storage control. The power and economic model of each unit in the micro grid is established, and a micro grid operation cost function is put forward. Thermoelectric coupling is avoided by classified management. The problem of power distribution between stored energy and thermalloads is solved. The control process is simplified. The realization of a management function by the micro grid energy management system is facilitated.

Description

technical field [0001] The invention relates to the technical field of energy management, in particular to an energy management method for a microgrid system including electric and thermal loads. Background technique [0002] In recent years, microgrids using distributed generation technologies and energy storage systems have become one of the most promising solutions to the problem of heating and power supply in rural areas. In some micro-grid systems, the generated electricity can not only meet the power demand, but also meet the heating demand. In addition to the renewable energy power generation system, this type of micro-grid also includes controllable heat loads, typically including heat loads The photovoltaic microgrid system structure is as follows figure 2 shown. Both energy storage and thermal loads in this type of microgrid system can be controlled by the energy management system (EMS) for power and energy. Relevant studies and applications have proved that com...
