Abstract

The invention discloses a photovoltaic power generation participant power local consumption method. The method includes the following steps that: household photovoltaic power generation power source installed capacity, historical output condition and grid-connected electric quantity are surveyed, household photovoltaic power generation quantity is determined according to historical electricity consumption conditions of regional users, and an objective function is formulated; based on historical data, current photoelectric power source output and electricity consumption conditions of the users are predicted, the electricity consumption characteristics and demand response characteristics of user-side controllable loads are analyzed according to predicted data, life habits of the users and the like; parameters such as energy storing device capacity and input/output power are designed according to the objective function and transferrable load electricity consumption characteristics; and finally, an energy storing device charge and discharge time-table can be formulated. With the local consumption method of the invention adopted, power quality of a power grid can be improved, economic benefits can be maximized, and the development of clean energy can be benefitted.

Description

technical field [0001] The invention relates to the field of new energy photoelectric grid connection, and in particular to the technology of on-site power consumption in which photovoltaic power generation participates. Background technique [0002] With the gradual depletion of fossil energy and the intensification of environmental pollution, many countries have intensified the development of renewable energy power generation in recent years, especially solar power generation, in order to alleviate energy and environmental problems. Solar energy has the characteristics of "low energy density, intermittent, and spatial distribution changes at any time", so its power generation output has the characteristics of intermittent and poor controllability. The big challenge has led to the widespread occurrence of the phenomenon of "light abandonment". The National Energy Administration pointed out that the proportion of domestic photovoltaic power stations being "abandoned light a...
