Problems solved by technology

Research on the impact of real-time pricing shows that household users have significant price elasticity, and customers respond to energy-saving peak hours, but do not increase average consumption; therefore, dynamic pricing as a price means can achieve electricity demand-side management, and analyze household internal and external Information, rescheduling and management of household load

specific Embodiment approach

[0061] The specific embodiment of the present invention comprises the following calculation steps:

[0062] (1) Firstly, establish a single objective function for energy management optimization, including the total energy consumption cost of users, total energy consumption, peak load and carbon emissions. Each objective function is expressed by the following formula:

[0063]

[0064]

[0065]

[0066] J 4 =Dmd·c dc

[0067] Among them, J 1 Represents the user's total energy consumption cost objective function, J 2 Indicates the user’s total energy consumption objective function, J 3 Indicates the carbon emission target function, J 4 Indicates the peak load objective function, t is the time mark, T is the time set T={1,...,96}, i is the load type, A is the family load set, li is the lighting load, esd is the energy storage device, pv Indicates the photovoltaic system, c ed (t) represents the electricity price at time t, P i Indicates the rated power of load of...

Abstract

Provided is a gateway modeling method for a household load energy management. The method comprises that an objective function of energy management optimization is established, using constraints of a load demand and operation constraints of each type of household load in each time interval are established, and the optimized operation state and power of the loads in different moments are calculated. Objects including the user comfort level, the minimal energy utilization cost, load demands and carbon discharge are taken into consideration simultaneously, the method has great guiding significance in practicality, and a new method and ideal are provided for power load management.

Description

technical field [0001] The invention relates to a modeling method for a household load energy management gateway, which belongs to the field of electric load management. Background technique [0002] Most existing DSM focuses on energy efficiency, dynamic pricing, and load control in terms of household loads. A related reported study of the impact of dynamic pricing on household loads shows that there is no direct relationship between customer behavior and implementation. For example, dynamic pricing can provide considerable net benefits, and the price elasticity of household users is significantly higher than that of other sectors. Hour-of-use pricing for half the peak load, resulting in a significant reduction in average monthly costs. Research on the impact of real-time pricing shows that household users have significant price elasticity, and customers respond to energy-saving peak hours, but do not increase average consumption; therefore, dynamic pricing as a price mea...
