Problems solved by technology

[0004] However, there are few researches on agricultural load. The existing ones take agricultural load as the research object, and propose a cold-heat-electric-gas rural multi-energy flow micro-energy grid architecture with biogas as the gas source, and establish an optimal dispatching of rural micro-energy grids. model, and ultimately realize the economic operation of rural micro-energy grids
In view of the rapid growth of the load of the current facility agriculture, the lack of an effective dispatching control method to realize the local consumption of photovoltaic power

Abstract

An embodiment of the invention provides a facility agricultural greenhouse and an optimal control method for multiform energy storage. A facility agricultural greenhouse structure is established, eachpower supply device and a power consumption model thereof in the greenhouse structure are established, and a coordinated optimal model taking photovoltaic output characteristics, time-of-use power price as well as energy consumption and storage characteristics of facility agricultural production into account is established by taking the lowest comprehensive electric heating operation cost of thefacility agricultural greenhouse as an optimization object. An example result shows that a phase change heat storage and energy storage device and a water storage and energy storage device realize themaximized in-situ consumption of excessive photovoltaics, reduce affects of photovoltaic delivery to the stability of a power distribution network and prove the reasonability of a scheduling controlmodel.

Description

technical field [0001] The invention belongs to the technical field of agricultural energy storage, and in particular relates to a facility agricultural greenhouse and a multi-form energy storage optimization control method. Background technique [0002] The demand for electricity in the vast rural areas continues to increase, especially with the development of facility agriculture, the electricity consumption of agricultural loads has increased sharply, providing a new option for the consumption of photovoltaic power generation. [0003] At present, there are many studies on the characteristics of industrial and commercial loads. For example, analyze the response characteristics of electric vehicle charging load, establish an evaluation model for electric vehicle charging load scheduling potential, realize the optimization of load curve, and improve the stability of power grid operation; through the calculation example of IEEE33 node distribution network, this method can ef...
