Power utilization decision optimization method based on opportunity cost loss value

Abstract

The invention discloses a power utilization decision optimization method based on an opportunity cost loss value, and the method is characterized in that the method comprises the following steps: S1, building a strategy set at a t moment and an event set at the t moment; s2, establishing a target power grid integrated energy system model; s3, performing data calculation on the target power grid integrated energy system energy consumption model in T time periods from the t moment to obtain a strategy sequence of T time points; s4, verifying whether the scheme of the T time points can meet the stability requirement of the power grid or not; if yes, taking the first strategy scheme of the strategy sequence as the power utilization strategy method of the next time point; if not, modifying model constraint conditions, and recalculating; and S5, repeating the steps at the moment t = t + 1 until the control cycle is ended, and effectively reducing the influence of the uncertainty of the event on the robustness of the power utilization strategy by using the computer to obtain the expected value of the loss value.

Description

technical field [0001] The invention relates to the field of power supply, in particular to an optimization method for power consumption decision-making based on opportunity cost loss value. Background technique [0002] As more and more inverter-type power supplies and power electronic equipment are connected to the grid, more and more grid-connected or independent grids will be formed at the terminal of the distribution network, which will bring far-reaching consequences to the operation and management of the distribution network. Impact. The biggest advantage of the power supply mode in the form of a grid is that it can independently and finely control the operating equipment in the grid to achieve the optimization of power distribution. With the introduction of the Energy Internet, the power grid is also developing towards an integrated energy system. The biggest difference is that the control of energy is no longer limited to electric energy, but also includes thermal ...

Problems solved by technology

[0005] The purpose of the present invention is to overcome that in the prior art, the traditional power utilization method cannot target the opportunity loss cost expectation value of different event benefit values, thereby increasing the uncertainty of the power supply system and causing an impact on the power utilization strategy and the robustness of power allocation. To increase the cost of the power supply company and reduce the efficiency of electricity use, provide a power consumption decision optimization method based on the opportunity cost loss value, calculate the opportunity loss cost expectation value of the same strategy for different event benefit values, and choose the smallest opportunity cost loss according to the maximum and minimum criterion The strategy corresponding to the value is taken as the optimal strategy
