Abstract

The embodiment of the invention provides an energy optimization scheduling method and system for a household multi-energy complementary comprehensive energy utilization system. The method comprises the following steps of: establishing an energy optimization scheduling model of the household multi-energy complementary comprehensive energy utilization system; wherein the energy optimization scheduling model takes the minimum total electric charge of a user and the highest system efficiency as targets, and takes the heat balance constraint, the electric energy balance constraint, the user conventional time-shiftable electric load daily electricity consumption constraint, the polymorphic energy storage constraint and the controllable heat source output heat constraint of a household comprehensive energy utilization system as constraint conditions; and according to the energy optimization scheduling model, optimally formulating each controllable heat source output heat plan, each morphological energy storage input and output energy plan and a user conventional time-shifting load work plan in each time period of the next day. According to the embodiment of the invention, each heat sourceequipment output energy daily plan, each energy storage input output energy daily plan and each time-shiftable load workday plan of the user are formulated, and the purposes of reducing the electriccharge of the user and improving the comprehensive utilization efficiency of energy are achieved.

Description

technical field [0001] Embodiments of the present invention relate to the field of electric power technology, and more specifically, relate to an energy optimization scheduling method and system for a household multi-energy complementary comprehensive energy utilization system. Background technique [0002] Under the new situation of promoting energy production, improving energy utilization efficiency, increasing energy conservation and emission reduction, and preventing smog, household "coal-to-electricity" projects in vast rural areas have been widely used, resulting in air-source heat pumps, electromagnetic A heating system that replaces coal with electricity, including auxiliary heat, semiconductor auxiliary heat, thermal storage electric boilers, and many other equipment; at the same time, renewable energy utilization equipment such as photovoltaic power generation and solar thermal collectors are installed on the majority of rural user buildings, forming A comprehensiv...
