“…The lifetime of VSI depends on the operating environment and load. P pv at input terminals reduces the life of VSI; however, the ESS, acting as a buffer, absorbs sudden changes in the power to increase the life of VSI [15,16]. Figure 10 shows the VSI loading with and without MESS.…”

This study proposes an energy management system (EMS) to manage a standalone hybrid power system (HPS) comprising solar photovoltaic (PV), proton exchange membrane fuel cell (PEMFC), and a battery energy storage. The battery and a hydrogen storage system in PEMFC provide short-and long-term electricity storage, respectively. The EMS ensures electrical efficiency during normal/abnormal operation of the HPS and related limitations, namely unexpected variations in solar irradiance and loads, PEMFC cold start, and battery charging status. The proposed EMS is evaluated using mathematical modelling, simulation studies, and real-time digital simulation. The results show that the proposed EMS is resilient to complex solar PV/load power changes and keeps the dc-link voltage in place. The viability of the proposed HPS is analysed using daily average solar insolation and load profiles. This analysis is useful to schedule problems of load/generation. The economic analysis of the proposed EMS, done using Homer pro, ensures that the HPS operates cost-effectively.

“…The inverter rated by their continuous wattage output.In terms of cost, thelarger they are, the more they cost. The inverter size is chosen so that its cost and inverter -related losses are minimized, i.e.it nominal power should be as small as possible, to provide high conversion effi ciency during normal operation [16]. From the Table 2, the total power of the household is 2,495 W, then due to a normal surge of fan and washing machine, the additional power of 1100 W at the start, making 3595 W. Thus the capacity for an inverter to be used must be 3595W.…”

To every system there is a boundary to its procedure, thus, a system operating at higher than its operating limit will decrease its lifespan and that can contribute to failure of the arrangement. This leads us to assessments and calculations of standalone PV-system component based on the fi eld assessment and performances in an area in Ibadan, Nigeria. Using relevant formulae to calculate the requirement of each element that makes up the stand-alone PV-system.The battery as an essential component of the microgrid, battery life depends on both depth and rate of discharge.The resolutions of this report refl ect the abused of components involves in the initiation of the system especially the battery. The paper suggested an intelligent system to take care of the excess loads at a particular time, which alsowill take into account priority of the appliances at the time in relation to the capacity and state of the battery to control the appliances.

Electrical power generation resources for green energy revolution have been the present state of the art. Photo Voltaic (PV) systems are of prime concern for solar energy extraction as an alternate source of power systems. Reliability analysis of such PV systems will be significant for future prediction and estimating the failure so as to improve the performance of the system. In this paper, a probabilistic method is used to evaluate reliability performance of solar array of a PV system. The system PV-Array includes cells, Modules, Strings. The cutset method is proposed to analyze real life grid-connected PV systems. Exponential failure rate of PV Cell is considered. For improved performance of the PV System, failure analysis has been done and the range of predicted failure rate of PV Cell is estimated to design for Reliability of the PV System array. Also evaluated, the reliability of the PV System using proposed method by neglecting higher order Cutsets. The computational results for presented by variation in failure rate of cell to designing for reliability of PV system array.
