The invention discloses an optimization method for a household energy management system and an optimization device. The method comprises steps that household loads are classified according to household load use modes to acquire a type of each household load; according to the meteorological data and the historical power consumption data of the household loads, the photovoltaic power consumption amount is predicted; an economical optimization model for realizing lowest cost and an environmental-protection optimization model for realizing lowest carbon discharge capacity are acquired according to the photovoltaic power consumption amount, preset restraint conditions, the electricity price data and the household load types; the optimization models reflect a work state of each household load at each time segment. According to the method, the photovoltaic power consumption amount of a user is predicted through the meteorological data and the historical power consumption data of the household loads in combination with the relationship between new energy power generation and the energy demand of the user, moreover, the economical optimization model and the environmental-protection optimization model are acquired in combination with the electricity price data, so all load work states are enabled to realize economical power consumption or environmental-protection power consumption to the maximum degree.
Description
technical field [0001] The invention relates to the technical field of smart grids, in particular to an optimization method and device for a household energy management system. Background technique [0002] At present, the development direction of the power grid in the world is to build a flexible, clean, safe, economical and friendly smart grid. The strong smart grid is an organic whole including power generation, power transmission, power transformation, power distribution, power consumption, dispatching and other links, and is a complete smart power system. Home users, as the end of the whole system, use advanced measurement technology, communication technology, automatic control technology, new energy technology and intelligent optimization decision-making technology to form a smart home energy management system. [0003] With the advancement of technology, more and more loads in smart homes are involved in the scheduling and management of energy systems. When there ar...
