Embodiment 1

[0050] In view of the volatility and instability in the current micro-grid operation, this embodiment intends to start from the power generation side, mainly considering the inertial factors of the cooling and heating loads in the combined cooling, heating and power supply system, and improve the micro-grid’s impact on wind power and photovoltaics. The consumption capacity and the economy of microgrid operation. The energy utilization rate of CCHP is high, which can improve the ability of the microgrid to absorb wind energy and solar energy. In addition to the energy storage equipment configured by itself, CCHP uses the inertia factors in its cooling and heating loads to construct a multi-element energy storage system, further optimizes the capacity allocation of system equipment, and improves the overall economic benefits.

[0051] This embodiment provides an optimal scheduling method for a microgrid considering combined cooling, heating and power, which is applied to a micro...

Abstract

The invention relates to a microgrid optimization scheduling method considering combined cooling heating and power supply. The method is used for optimizing the operation of the combined cooling heating and power supply micro-grid. The micro-grid comprises a fan, a photovoltaic generator and a micro gas turbine; according to the method, an improved butterfly algorithm is adopted to solve a pre-established microgrid optimization model, and the optimal solution is obtained; the micro-grid is provided with a storage battery for supplying power to the micro-grid when the fan and photovoltaic power generation are insufficient, and the improved butterfly algorithm optimizes an elitist butterfly population through a reverse learning strategy and optimizes a random number through a chaos function. Compared with the prior art, the comprehensive energy utilization rate of the micro-grid system is improved by utilizing multi-energy complementation, the energy storage capacity of each device in the system is reduced, and the operation cost of the micro-grid is reduced; through the improved butterfly algorithm, the convergence rate and reliability of solving the micro-grid optimization model are improved.

Description

technical field [0001] The invention relates to the field of micro-grids, in particular to a micro-grid optimization scheduling method considering combined cooling, heating and power supply. Background technique [0002] Combined cooling heating and power (CCHP) system has three kinds of energy of cold, heat and electricity, which can improve the comprehensive utilization rate of energy and reduce pollutant emissions, and has good social and economic benefits. The microgrid solves the problem of large-scale access of distributed power to the power grid, and can effectively and flexibly utilize various distributed energy sources. The CCHP microgrid has a balance relationship between cold, heat and electricity, while the microgrid has two modes of grid-connected and islanded operation. Based on the consideration of energy utilization and economic benefits, how to formulate the best optimal scheduling strategy under the premise of meeting the cooling and heating loads of the s...
