A Robust Battery Grouping Method Based on a Characteristic Distribution Model
نویسندگان
چکیده
The inconsistent characteristics of individual power batteries in a battery pack can seriously affect the performance and service life of the whole pack. Battery grouping is an effective approach for dealing with the inconsistency problem by grouping batteries with similar characteristics in the same battery pack. In actual production, the battery grouping process still relies on the traditional manual method, which results in high labor and time costs. In this paper, a robust and effective battery grouping method based on the characteristic distribution model is developed. Specifically, a novel characteristic distribution model is proposed to determine the grouping priority of different batteries. Then, an improved k-nearest-neighbor algorithm is used to decide which batteries should be group into the same battery pack. Experimental results demonstrate the effectiveness of the proposed method.

Encouraging household investors to install distribution level battery storage systems using incentive prices
In this paper a bi-level optimization approach is introduced to increase the participation of household investors to install battery storage systems in the distribution level. The incentive prices are used here to encourage the private investor. In the upper level the viewpoint of the government is modeled in which, the peak shaving is the goal while minimizing the cost due to the allocated sub...
متن کاملRobust DEA under discrete uncertain data: a case study of Iranian electricity distribution companies
Crisp input and output data are fundamentally indispensable in traditional data envelopment analysis (DEA). However, the real-world problems often deal with imprecise or ambiguous data. In this paper, we propose a novel robust data envelopment model (RDEA) to investigate the efficiencies of decision-making units (DMU) when there are discrete uncertain input and output data. The method is based ...
متن کاملA Robust Scenario Based Approach in an Uncertain Condition Applied to Location-Allocation Distribution Centers Problem
The paper discusses the location-allocation model for logistic networks and distribution centers through considering uncertain parameters. In real-world cases, demands and transshipment costs change over the period of the time. This may lead to large cost deviation in total cost. Scenario based robust optimization approaches are proposed where occurrence probability of each scenario is not know...
