Abstract
This paper investigates the concept of temporal and spatial complementarity of wind and solar resources in Lower Silesia (south-wester 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.
Highlights
The advent of large scale variable renewable energy sources (VRES) mainly in form of photovoltaics and wind turbines is a result of a transition from power system based upon finite fossil fuels to a sustainable one utilizing the abundant and inexhaustible renewable resources
After that we have investigated the value of the coefficient of correlation between aggregated wind and solar energy yield as well as the observed load on an hourly, daily and monthly time scale
This implies that from the perspective of the whole voivodeship it is very unlikely that the wind or solar generation will follow the load profile. This will result in a situation in which energy surpluses and deficits will occur
Summary
The advent of large scale variable renewable energy sources (VRES) mainly in form of photovoltaics and wind turbines is a result of a transition from power system based upon finite fossil fuels to a sustainable one utilizing the abundant and inexhaustible renewable resources. The aim of this paper is to present the current state of the art in area of studies on the temporal and spatial complementarity between wind and solar energy sources. Both from the worldwide and national (Poland) perspective. Apart from assessing their complementarity on an hourly, daily and monthly time scale we will address the problem of their relation to the load curve
