Problems solved by technology
One is to limit the number of charge-discharge conversions of the battery within the scheduling cycle. However, the specific number of times needs to be set according to the actual situation, and its specific value is not easy to determine
In addition, it may happen that the battery cannot fully play the role of mitigating load changes due to too strict frequency limit, and the economy is poor; or a certain discharge power is too large, the discharge depth is large, and the service life is shortened
Therefore, it is not very reasonable to blindly pursue the reduction of battery charge and discharge conversion times to prolong battery life.
The second is to limit the amount of charge of the battery within a certain range, but this method does not consider all factors and does not take into account the specific impact of the amount of charge, it is only a qualitative control

The invention discloses a micro grid operation method considering demand response and energy storage collaborative optimization, which relates to the technical field of micro grid operation optimization. The method comprises the following steps: S1, establishing a model considering demand response and energy storage collaborative optimization for a micro grid; and S2, calculating the optimal valueof the collaborative optimization model, and obtaining an operation scheme of the micro grid. For the demand response model, the response cost of users is fully considered, and compensation is made according to the user's response enthusiasm to stimulate the user's enthusiasm to participate in the demand response. For the problem of high life loss of battery devices, the operation cost of batteries is constructed by studying the factors affecting the battery life and considering the influence of the state of charge of a battery having the greatest impact on economic scheduling, so as to achieve an effect of quantitative control.
Description
technical field [0001] The invention relates to the technical field of optimized operation of micro-grids, in particular to a method for optimizing the operation of micro-grids in consideration of demand response and energy storage. Background technique [0002] Demand response (DR) refers to a kind of electricity consumption behavior in which users change their regular electricity consumption habits after receiving electricity price signals or incentive signals from operators to alleviate the shortage of power supply. DR can be divided into incentive type DR and price type DR. The introduction of demand response in the microgrid will ensure that both the power supply side and the demand side meet the best operating conditions, which can improve grid flexibility to a certain extent and alleviate the impact of intermittent renewable energy, helping to establish a more economical and reliable microgrid. [0003] At present, there are many research results in domestic and for...
