Temporal and spatial complementarity of wind and solar resources in Lower Silesia (Poland)

Abstract

Abstract.This paper investigates the concept of temporal and spatial complementarity of wind and solar resources in Lower Silesia (southwester Poland). For the purpose of our research we have used hourly load and energy yield from photovoltaics and wind turbines covering period 2010-2014. In order to assess the spatial complementarity we have divided the considered voivodeship into 74 squared regions with maximal area of 400 km 2 . The obtained results indicate an existence of temporal complementarity on a monthly time scale and a positive correlation between load and wind generation patterns (also on a monthly time scale). The temporal complementarity for hourly time series in relatively low but has potential to smooth the energy generation curves.

Assessing temporal complementarity between three variable energy sources through correlation and compromise programming

“…Wind speed and solar irradiation time series for this area correspond to satellite measurements [54,55] . It is worth noticing that previous studies in the area have demonstrated a good fit between this records and ground data [32]. The data maps describing the behaviour of these two resources along the 8784 hours of 2008 are shown in Figure 3 (wind speed) and Figure 4 (solar irradiation).…”

“…Jurasz et al [32] analysed the complementarity of solar and wind energy over Lower Silesia in Poland. In their follow-up study [33] they presented how complementarity between solar and wind resources, coupled with pumped storage hydropower, can be used from the perspective of guaranteeing power system reliability.…”

A review on the complementarity of renewable energy sources: Concept, metrics, application and future research directions

“…The most common purposes for calculating the Pearson correlation coefficient regarding energetic complementarity has been: 1) conducting an statistical analysis for evaluating if the renewable energies available in one region could allow the configuration of efficient power systems based on renewables ( [15], [17], [18], [19], [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34]); 2) as a tool for improving the operation or planning of existing power plants or systems ( [12], [13], [35], [36], [37], [38]); 3) as part of the set of equations, parameters and inequalities in an optimization model ( [39], [40], [41], [42], [43], [44], [45], [46]).…”

The use of photovoltaics and electric vehicles for electricity peak shaving in office buildings

“…The load was obtained from on-site measurements and both atmospheric parameters were downloaded from (http://www.soda-pro.com/) which shows a good fit with on-ground measurements [6]. Figure 1 visualizes the normalized weekly power demand pattern in the considered office building.…”
