Photovoltaic all-electric kitchen and energy management optimization system

Abstract

The invention provides a photovoltaic all-electric kitchen and an energy management optimization system. The system is composed of a photovoltaic cell, a main control device, a storage battery, an all-electric kitchen cooker mounted on an alternating current bus and an all-electric kitchen water supply system. The main control device of the system takes STM32 as a controller, an optimization management method is embedded in the STM32 controller, and the method comprises the following steps: firstly, concluding the operation working rule of the water supply system, analyzing the load flexibility and the energy storage characteristic of the water supply system, and evaluating the energy storage potential of the water supply system; secondly, regarding the water supply system as a virtual energy storage system, and forming a multi-source energy storage system together with a storage battery energy storage system; establishing a digital twin model for photovoltaic power generation power prediction and kitchen load prediction, so that the prediction precision is improved through virtual-real interaction; and finally, on the premise of considering source load storage scene classification, carrying out optimization operation on the system model by utilizing a non-dominated sorting genetic algorithm, and establishing an all-electric kitchen energy management model by taking charging / discharging of the multi-source energy storage system as a scheduling means by taking improvement of economy and stability of all-electric kitchen operation as a target. An optimal scheduling scheme issolved by using an intelligent search algorithm, so that a function of merging into a local power grid when the electric energy yield is excessive is achieved. Economic and stable operation of the all-electric kitchen is ensured while virtual and real data intercommunication is realized.

Description

technical field [0001] The invention relates to the field of photovoltaic all-electric kitchen and energy management optimization, in particular to a photovoltaic all-electric kitchen and energy management optimization technology. Background technique [0002] With the increasingly serious energy crisis and environmental pollution, solar photovoltaic power generation, as a clean green energy, has become a focus of attention and research around the world and has been gradually extended to people's daily life. The independent grid connection of distributed power stations has become a microgrid. major trends in development. [0003] Photovoltaic all-electric kitchen refers to a kitchen in which all energy-consuming equipment in the kitchen abandons traditional fossil energy and uses photovoltaic power generation as the only energy source, and is capable of meeting all cooking methods and production needs. Its biggest advantage is energy saving, high efficiency, safety and reli...
