Cornell University. Thi Ngoc Nguyen et al. Due to the stochastic nature of photovoltaic PV power generation, there is high demand for forecasting PV output to better integrate PV generation into power grids. Systematic knowledge regarding the factors influencing forecast accuracy is crucially important, but still mostly unknown. In this paper, we review papers on PV forecasts and extract a database of forecast errors for statistical analysis.

During the winter schedule the blog is updated once every week. Snow accumulation forecasts replace precipitation forecasts. Also, there is renewed emphasis on ice and snow boundary conditions and their influence on hemispheric weather. Snow accumulation forecasts will be replaced by precipitation forecasts. Also, there will be less emphasis on ice and snow boundary conditions and their influence on hemispheric weather.

In Figure iii, I show the observed surface temperature anomalies for December, January and February with the three different winter forecasts shown back in November As I describe below looks like a cold sandwich with warm to the north and south. Everyone should make their own impression, but I do think that the AER forecast performed best. At least the initial impacts from the large polar vortex PV disruption are building cold in Canada while most of Europe remains mild see Figure 9. Europe could turn colder if the more traditional impacts occur in very late March but more likely in April. I do think that the Arctic forcing is better for weak PV in late winter then it was in late Fall and early winter and may have played a role. Though even if the resultant weather is not that notable or memorable the PV disruption is very interesting. From the latest polar cap geopotential height anomalies PCHs forecast maybe the influence of the SSW reaches the troposphere the very last days of March see Figure Yet all the mdoels are in consensus that the pattern will turn colder across North America next week, with potentially widespread and deep cold air pooling across Canada that should enter the Contiguous US Lower 48 to some degree with models disgreeing on the strength of the cold air in the US.

Near-Term T his week The AO is predicted to be positive this week Figure 1 with mostly negative geopotential height anomalies across the Arctic and with mixed geopotential height anomalies across the mid-latitudes of the NH Figure 2. Pv forecast twitter Market Insight Report Archives.

As more states and utilities create and expand community solar programs, access to solar will expand to all types of households and businesses. Since the beginning of , more than GW of solar module manufacturing capacity has been announced, along with dozens of facilities producing other components of the supply chain. Figure 6. Last week I showed the polar cap geopotential height anomalies PCHs with the upward and downward influences associated with large PV disruptions but only minor SSWs and also shown in solid arrows are the downward propagation of the major SSWs. Arctic sea ice extent grew again slowly this week. For Europe the source of cold air in Siberia is depleted after dumping into East Asia, so that would likely need to replenish first. And for me it is Siberia that may be more than any other region, the battleground on whether there is influence from Arctic change that extends to the continents. From our energy diagnostics it does seem that wave reflection is occurring and contributing to the expanse of cold across North America. In the interim Europe and the Eastern US have turned exceptionally mild. Numbers explained in 4 December blog. Observed and predicted daily polar cap height i.

Widespread warmth rules but also relatively cold in Alaska and adjacent Canada, Scandinavia, Northwest Russia, widespread across Siberia and now Eastern China see Figure. Join today! PV splits are thought to more reliably to impact the tropospheric circulation related to a negative NAO. Because of their outsized portion of the market, policy and incentive changes in any of those states could rattle the market and stymie national growth. Figure 4. Mild temperatures will support snowmelt Southern Canada and the higher elevations of the Western US this period Figure This pattern favors widespread normal to above normal temperatures across Western and Northern Asia with normal to below normal temperatures across Southwestern, Central and East Asia the next two weeks. Greenland blocking can support unseasonable cold weather across Northern Europe and above normal snowfall. Observed and predicted sea level pressure anomalies hPa shading from 1 February — 26 February based on GFS initializations and the GFS forecast from the 26 February forecast. Models seem to be schizophrenic on whether the PV will split or not and to me both scenarios seem plausible.
