Family load optimized dispatching method based on demand response

Abstract

The invention discloses a family load optimized dispatching method based on demand response. The family load optimized dispatching method is characterized by comprising the following steps: 1, dividing family loads into transferable loads and non-transferable loads according to load characteristics; 2, establishing a target function of a family load optimized dispatching model considering a power consumption cost, an incentive income and inconvenience comprehensively according to the transferable loads; 3, determining constraint conditions of the family load optimized dispatching model, and forming a family load optimized dispatching model based on demand response together with the target function; and 4, solving the family load optimized dispatching model through a binary particle swarm optimization, and obtaining an optical dispatching result of the transferable loads. By adoption of the family load optimized dispatching method disclosed by the invention, the optimized dispatching of the transferable loads in the family can be realized, the transferable loads within a peak electricity price time period are transferred to a valley electricity price time period and a common electricity price time period, thereby reducing the family power consumption cost, realizing a peak shaving and valley filling function of the power grid, and thus the operation security and stability of the power grid in the time division electricity price environment.

Description

technical field [0001] The invention relates to the field of demand response, in particular to a demand response-based family load optimization scheduling method. Background technique [0002] With the growth of population and the improvement of people's living standards, energy consumption in the residential sector has accounted for 30-40% of the world's total energy consumption. As an important part of energy consumption, the daily load of households often presents a peak load in a period of time. However, in order to meet the power consumption during the short peak load every day, the power generation side needs to further expand the power generation capacity, which brings a huge cost burden to the operation of the power system. From the perspective of demand side management, demand response means that power users respond to price signals or incentive mechanisms to change some of the original power consumption behaviors, thereby promoting the optimal operation of the powe...

Problems solved by technology

[0003] In the existing demand-side management schemes, the household load optimal dispatching method often does not consider the inconvenience brought to users after the household load optimal dispatching, which makes the objective function of the household load optimal dispatching model not perfect and does not conform to the actual situation ; At the same time, when considering the impact of incentives on optimal scheduling of household loads, existing schemes often use fixed incentives for each time period, which is not conducive to users transferring more load from peak electricity price periods to valley electricity prices and normal times Electricity price period, which makes the effect of peak shaving and valley filling not very obvious
