“…This analysis is in agreement with previous studies that show summer days on average have substantial solar resources available during their daily peak load hours, as seen in Fig. 6 [2], [11], [15], [19], [25]. This analysis is unique because it demonstrates that this correlation between peak load and solar availability reduces the inter-annual variability of peak residual load values as more solar generation is deployed.…”

Electric power systems in many parts of the world are undergoing a transformation from relying almost exclusively on dispatchable power (e.g., fossil, nuclear, and large hydropower) toward incorporating more variable nondispatchable generation (e.g., wind and solar PV). We show for the first time that solar generation can decrease some aspects of variability in the peak residual load in power systems. The electric load minus generation from nondispatchable resources is known as the "residual load." The maximum or peak residual load provides an estimate of the quantity of dispatchable generation capacity required to supply electric load during all hours. We study the peak residual load as a function of increasing wind and solar generation for three power systems in the U.S.: the PJM system in the Mid-Atlantic, the ERCOT system in Texas, and the NYISO system in New York. We analyze more than a decade of historical data for each region. The introduction of variable renewable power is often thought to increase the variability of most characteristics of power systems. Contrary to this idea, we show the inter-annual variability in peak residual load decreases for all three systems as a function of increasing solar generation. We attribute this effect to correlations between solar generation and peak electric load values. Peak electric load values for all three systems occur during summer heat waves, when air conditioning is used. We find that as solar generation increases, the quantity of dispatchable generation capacity needed to supply the residual load becomes more similar year-to-year. Therefore, in some systems, expansion of variable solar generation can increase predictability of the peak residual load. Thus, an increase in solar generation could ease achievement of certain system reliability targets.

“…Globally, a great deal of technological progress has been made in lowering the levelized cost of electricity generated from solar and wind [19,20] . The technical solution are evolving for the development of a super battery that can store wind electricity generated when it's not needed and act as an energy bank for dispatching when needed, also, smoothing its output as a solution to the reliability setback of wind power [21,22]. Therefore, the SMART acronym of sustainability, reliability and affordability in the energy field could be resolved within the short-and long-term niche of technology advancement.…”

Wind power production has increased by a hundredfold during the last 20 years and represents roughly 3% of the total global electricity production. In recent years, technological changes in wind turbine configurations have enabled higher capacity factors for wind turbines. The results from the studies showed that wind as a source of energy for Växjö could be explored in order to achieve the goal of energy sufficiency and as well as sustaining the greenest city status in Europe. The simulation showed that 100 MW electricity could be generated from the wind sources with respect to the available data via global wind metrological data, literature, RETScreen Expert software., LCOE and IRR analysis tools. In addition, the Internal rate of return (IRR) of 8.7% which is good enough considering the proposed energy tax, energy security and environmental benefit cost ratio as well as reduced global weighted-average levelized cost of electricity (LCOE) from wind power technology make it more attractive for investor-Växjö municipality.

“…across TSOs in several neighboring countries [27]. In fact, while the aggregated variability of wind and solar is in general less than that of each resource alone, it is extreme weather conditions, such as storms, that often lead to the largest forecast errors [28]. A recent study concludes that, over the last decade, increasingly accurate weather forecasts have saved consumers over $150 million in annual energy savings [29].…”
