A Multi-Dimensional Evaluation Method for Power Generation Characteristics of Renewable Energy Stations with Energy Storage Systems

Three-Dimensional Fuzzy Logic Applied to DC Voltage Regulation in Active Power Filter of PV System

“…Fuzzy three-dimensional logic, also known as 3D fuzzy logic [8][9][10][11][12][13][14][15][16], is an extension of traditional fuzzy logic that allows for modelling three-dimensional systems using threedimensional fuzzy sets.…”

“…In 1992, Kaoru Hirota proposed a solution to this problem in a paper titled "Three-Dimensional Fuzzy Control." [12][13][14][15] Hirota's approach involved dividing a three-dimensional fuzzy set into a series of two-dimensional slices, each of which represented a different level of membership in the set. By representing the fuzzy set in this way, it was possible to perform calculations more efficiently and accurately.…”

“…The efficiency of many commercial modules is not constant and depending on the illumination. This phenomenon is very often neglected by the manufacturers, who give no indication of the behavior of their module at low illumination; [12] [14] the following curves in "Figure 11" shows the variation in power values given by a 250 Wp PV panel under standard conditions at a fixed temperature T equal to 25°c variable during the variation in irradiation (a) then T variable with 1000w/m² (b). The power delivered by a PV depends on the ambient temperature, the wind speed, the mounting of the module (integrated in the roof or ventilated) and all these parameters change according to the chosen site for modules installation.…”

“…In addition, the coefficients linked to the temperature differ according to the materials used for the manufacture of the module. [12] Temperature is a very important parameter in the behavior of PV cells [13]. "Figure 11" (b) Describes the behavior of the module under a fixed illumination of 1000W/m 2 , and at temperatures between 15°c and 40°c.…”
