Random scheduling optimization method for electro-thermal coupling micro-energy station

Abstract

The invention provides a random scheduling optimization method for an electro-thermal coupling micro energy station, and the method comprises the steps: firstly, building a virtual micro energy station and an output model of the virtual micro energy station, wherein the virtual micro energy station comprises a power subsystem, a thermal subsystem and an energy storage subsystem; secondly, constructing a target function according to the operation income of the power subsystem, the thermal subsystem and the energy storage subsystem; constructing a risk function of virtual micro-energy station scheduling by using a CvaR method, and constructing a random constraint condition by using a robust random optimization theory; and finally, optimizing the random scheduling of the micro-energy stationby utilizing the maximization of the target function and the minimization of the risk function. The PBDR is implemented to realize optimal operation of the VEP, and the reasonable peak-valley price difference is set to stimulate the user to respond to the energy scheduling of the VEP so as to consume WPP, PV and SC clean energy output, reduce clean energy waste to the maximum extent, and obtain the maximum economic benefit of the VEP while minimizing the operation risk level.

Description

technical field [0001] The invention relates to the technical field of micro-energy station dispatching, in particular to an electrothermal coupling micro-energy station random dispatching optimization method. Background technique [0002] Energy is an important pillar of economic development. In recent years, global energy demand has grown rapidly, non-renewable energy represented by coal and petroleum is increasingly exhausted, and safety issues restrict the development of nuclear energy. Energy issues have gradually become a major concern of countries all over the world. In the face of many problems such as rising energy prices, unstable supply, low utilization efficiency and insufficient consumption of renewable energy while the energy is developing rapidly, it is imperative to explore the comprehensive utilization of multi-energy. [0003] The core idea of ​​multi-energy coordinated optimal dispatch for smart grid parks is to coordinate and consider various energy supp...
