摘要：
The selection of energy storage is an important part of energy storage planning, which pursues the applicability of technology and the economy of investment cost. The process involves multiple decision index, and with incomplete information, qualitative and quantitative information doping and so on, so it is a complex decision problem with multi objective and multi attribute. Analytic hierarchy process (AHP) is a combination of qualitative and quantitative analysis, systematic, hierarchical analysis method, and it can be used to solve the problem of energy storage selection. The basic data of energy storage technology are presented in the form of interval or qualitative description, so the interval analytic hierarchy process (IAHP) which is a combination of interval numbers and analytic hierarchy process is adopted to improve the operability of the selection scheme. In the process of building selection model using the IAHP method, because there are not enough quantitative data to be used as a decision-making basis, subjective and objective combination weighting method is chosen for determining the weight of the index. Firstly, the weight of the first level decision index is determined based on the expert’s experience. Then, the difference of the response degree of the energy storage technology to the expected value of the working condition is considered to determine the second layer decision weights based on entropy method. Finally, the verification of the scheme is carried out, in the condition of stabilizing output fluctuation, based on a 20 MW PV power plant. The results show that the applicability of lithium battery is highest, the second is the liquid flow battery and the common lead acid battery, the sodium sulfur battery, the colloid battery and the lead carbon battery are relatively poor. Through the case analysis, it is proved that the method can realize the comprehensive quantitative comparison between different energy storage types, which can provide technical support for the energy storage planning in the theoretical method. © 2016, High Voltage Engineering Editorial Department of CEPRI.
