“…Recent research has been devoted to the reliability performance of power electronic components [11]- [12], converters [13]- [15] and systems [16]- [17]. However, the reliability research in the area of power electronics has the following limitations: DFR process discussed in [10] is too broad in focus which could not reveal the specific challenges and new opportunities for reliability design of power electronic systems; over reliance on the value of Mean-Time-BetweenFailures (MTBF) which is found to be inappropriate to most practical cases as discussed in [4] and [18]; and over reliance on handbook-based models and statistics.…”

Abstract-Advances in power electronics enable efficient and flexible interconnection of renewable sources, loads and electric grids. While targets concerning efficiency of power converters are within reach, recent research endeavors to predict and improve their reliability to ensure high availability, low maintenance costs, and therefore, low Levelized-Cost-of-Energy (LCOE) of renewable energy systems. This paper presents the prior-art Design for Reliability (DFR) process for power converters and addresses the paradigm shift to Physics-of-Failure (PoF) approach and mission profile based analysis. Moreover, the lifetime prediction of reliability-critical components IGBT modules is discussed in a 2.3 MW wind power converter. Finally, the challenges and opportunities to achieve more reliable power electronic converters are discussed.

“…The natural variability of environmental conditions and nonlinear behavior of photovoltaic generators make the utilization of photovoltaic energy a challenging task [1][2][3][4]. The increasing penetration of renewable sources with power-electronic interface in the power systems is raising technical problems in various areas such as power quality control [5][6][7], voltage regulation [8], grid protection coordination [9,10], loss of mains detection [11,12], and generator operation following disturbances on the distribution grid [13][14][15].…”

Abstract:The increasing penetration of renewable sources with power-electronic interfaces in power systems is raising technical problems and the overall efficiency of photovoltaic systems can decrease dramatically. In this context, the optimal layout for the photovoltaic system is required. The most adequate strategy to connect the renewable system to the electrical power grid or to supply the end users must be adopted. The present paper proposes a design layout of a PV plant using a DC bus system to improve the overall energy conversion efficiency. An analysis of steady-state system stability, voltage drop and DC cable conduction losses is conducted. The leakage currents to the ground are investigated through simulations. Experimental results are shown focused on the analysis of optimal layout of photovoltaic systems under particular operating conditions.

Abstract. The paper proposes processing and interpretation of the thermo-graphical images acquired on a grid-connected photovoltaic plant (20 kWp). Infrared analysis allows a reliable evaluation of the state of health of the plant and at the same time the detection of the actions needed of the maintenance. In particular the identification of possible differences between the strings and the rapid location of local hot spots, breakdowns or other problems are presented.
