A continuous task load energy control method for intelligent electricity consumption

Abstract

The invention discloses an intelligent electricity consumption oriented continuous task type load energy control method. The method comprises the following steps: constructing a continuous task type load model; constructing an energy control optimized decision model; solving the continuous task type load model and the energy control optimized decision model. According to the method, the use time of the load in the high electricity price time period is shortened, and the load is transferred to the time period when the distributed energy resource electricity generation is prominent, so that the total load curve can be improved; a part of distributed energy resource electricity generating capacity is transferred by a peak-clipping valley-filling manner of an energy storage device, on the one hand, the proportion of elimination on the spot of the distributed energy resource electricity generating capacity can be increased, the wasteful power grid access manner of the surplus electric quantity can be avoided, and the better economic efficiency can be obtained; on the other hand, the adverse effects of the distributed power supply on the power grid access can be reduced, and the method is favorable to the safe and stable operation of the power grid.

Description

technical field [0001] The invention relates to the field of intelligent electricity utilization, in particular to a continuous task load energy control method for intelligent electricity utilization. Background technique [0002] Facing the increasingly severe energy situation and increasingly embarrassing environmental protection status, China has formulated relevant policies and development plans to vigorously develop renewable energy. One of the important goals is to increase the acceptance of renewable energy, especially solar photovoltaic power generation, on the user side. Income capacity, to achieve parity grid-connected photovoltaic system on the user side. [0003] With the development of smart grid technology and the implementation of distributed photovoltaic grid access policies, various users have begun to try to introduce distributed new energy. However, due to the large mismatch between the output of most new energy sources such as photovoltaics and the user ...

Problems solved by technology

However, due to the time mismatch between the output of most new energy sources such as photovoltaics and user load consumption, the utilization rate of new energy is low, and the comprehensive rate of return on the user side is low.

What's more serious is that the new energy introduced in large quantities has a wide range of intermittent nature, which will have a negative impact on the distribution network. If the system planning is unreasonable or the supporting scheme is not perfect, power supply failures will easily occur.
