Customer ServiceIt is easy to tell from the formula for leakage current (shown above) that the larger the PV panel area(S), the higher the conductivity(ε) of air, and the shorter the distance(d) between the PV panel and ground or roof, the higher the leakage current will be. This is the reason why commercial solar PV projects, especially when the solar panels are "carpet"
Customer ServiceThere are two distinct methods to eliminate the leakage current in the solar PV array system: (i) obstruct the leakage current, (ii) reduce the variation/constant common-mode voltage. The additional diodes/switches are incorporated in the system to obstruct the leakage current by disconnecting the PV array from the grid side network.
Power reserve control of solar photovolt. The growing share of photovoltaic (PV) installations in power systems, with the consequent reduction in system inertia, has necessitated considering PV systems to participate in grid ancillary services such as fast frequency response (FFR).
Power reserve control (PRC) of PV systems, to create the required reserve power, needs the PV systems to be operated at a point below the maximum-power point. This paper presents a novel power-command tracking algorithm for PV systems to realize PRC operation.
Power curtailment of grid-forming photovoltaic (PV) sources to provide power reserves is a promising solution to deal with significant survivability challenges in PV microgrids. A control scheme is presented that is capable of providing both maximum power point (MPP) estimation and active power reserve regulation for grid-forming PV sources.
Therefore, the leakage current is attained within permissible limits as per the revised VDE-00126-01 standard as evinced in Fig. 6a. Fig. 6b and Figs. 7a and b show the response of SECS at the variation of solar irradiation from 1000 to 800 W/m 2.
The comparative analysis with the state-of-the-art techniques shows the effectiveness of the strategy. Under all test conditions, the harmonics in grid currents are observed within limits as per the IEEE-519 and IEC-61727 standards, whereas the PV leakage currents are maintained well within the range recommended by VDE-00126 standard.
