Embodiment Construction

[0026] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings.

[0027] In the day-ahead power market electricity trading, due to the duality of production and sales users, they can either sell electricity or purchase electricity. When there are multiple users selling electricity at the same time, the price of electricity sellers often determines their revenue, and also affects them. The payback period of its configured energy storage. In the same micro-grid, different users have different photovoltaic installation capacity and different energy consumption habits, making users have the prerequisites for electricity trading. Therefore, it is very necessary to add energy storage devices to the electricity trading between photovoltaic users to optimize the power allocation of users. This patent introduces th...

Abstract

An electric energy transaction model suitable for an optical storage type user comprises the steps that photovoltaic production power and load energy consumption data of the user are predicted on thebasis of photovoltaic, load and energy storage data of family historical users, the production-storage-energy consumption ratio of each user at different moments before the day is calculated, and evaluation of the tradable electric quantity by the user is obtained; according to the established user expected revenue function, the optimal quotation of the user in the quotation interval is determined, and a user electricity purchasing and selling strategy is determined based on a queuing method; and efficient configuration of user electric energy is further realized through user energy storage adjustment. According to the invention, a novel electric energy transaction model is formulated innovatively, the participation enthusiasm of the user is stimulated, the income of the user is improved,possibility is provided for popularization and development of a user side energy storage device, and the influence on a power grid is effectively inhibited while a new absorption way is provided for high-proportion distributed renewable energy sources.

Description

[0001] The invention belongs to the field of electricity market transaction algorithms, and specifically relates to an electric energy transaction model suitable for optical storage users. Background technique [0002] The access of renewable energy on the user side brings clean energy to users, greatly reduces the user's dependence on the power grid, and is conducive to environmental protection. However, with the high penetration rate of distributed renewable energy, its intermittent, volatile, and highly affected characteristics by external factors are very harmful to the power grid. As we all know, energy storage systems can smooth the fluctuations caused by photovoltaic power generation to the grid through charging and discharging. The current research on energy storage has been very mature, but energy storage systems are expensive, which hinders their large-scale coverage on the user side. At the same time, with the high penetration of distributed renewable energy, tradition...
