Abstract
Sumber energi terbarukan dapat digunakan sebagai pengganti sumber
energi tidak terbarukan seperti batu bara dan minyak (bahan bakar fosil) untuk
mengurangi emisi karbon dalam melengkapi kebutuhan energi. Dalam penelitian
ini, energi tersebut dihasilkan oleh Pembangkit Listrik Tenaga Surya (PLTS),
Pembangkit Listik Tenaga Bayu atau Angin (PLTB), dan Pembangkit Listrik
Tenaga Air (PLTA) yang datanya dimulai dari 1980 hingga 2012 di 12 negara
yang tersebar di benua Eropa yaitu Norwegia, Finlandia, Yunani, Spanyol
(Andalusia dan Galisia), Tunisia, Prancis, Romania, dan Belarusia. Tujuan
penelitian ini adalah untuk menganalisis karakter dan kelangkaan energi yang
didasarkan pada fluktuasi sumber energi.
Data yang digunakan dalam penelitian ini adalah serial data produksi
dan kebutuhan energi yang diperoleh dari konversi data meteorologi pada setiap
sumber energi seperti kecepatan angin, radiasi matahari, temperatur, dan debit
sungai. Analisis kelangkaan energi dilakukan melalui perhitungan statistika
dasar, RRV (Reliability, Resiliency, and Vulnerability), dan indeks kelangkaan
energi. Indeks ini didefinisikan sama dengan metode indeks kekeringan
presipitasi yang didasarkan pada data yang telah distandarisasi dan ambang
batas (garis ambang batas konstan atau harian).
Berdasarkan hasil perhitungan melalui garis ambang batas harian,
energi terendah yang dihasilkan dari PLTS terjadi pada 1982, 1997, dan 2011,
PLTA terjadi pada 1991 dan 1996, dan PLTB terjadi pada 1996 dan 2000.
Sedangkan berdasarkan garis ambang batas konstan, produksi dari PLTA
mencapai titik terendah pada 1989, 1992, dan 2003, PLTB pada 1994, 2009, dan
2012, dan PLTS pada setiap musim dingin. Selain itu, berdasarkan grafik indeks
kelangkaan energi, pada 1995 hingga 1997, produksi energi mencapai titik
terendah pada seluruh sumber di seluruh wilayah studi. Kelebihan kebutuhan
energi di seluruh negara terjadi pada tahun 2005.
===============================================================================================
Renewable energy resources can be used as substitutes of non-renewable
sources such as coal and oil (fossil fuel) in order to get lower carbon emission in
completing the energy demand. In this report, the renewable resources are solar
power, wind power, and hydropower from 1980 to 2012 in twelve regions among
European countries; Norway, Finland, Greece, Spain (Andalucia and Galicia),
Tunisia, France, Romania, and Belarus. The aim of this report is to characterize
and analyze the energy scarcity due to the cofluctuation between those
intermittent sources.
We used the chronological time series of energy production obtained for
each intermittent energy from converted meteorological variabels data such as
wind speed, irradiance, temperature, and river flow. The analysis of energy
scarcity in this report was made from basic statistic, correlation analysis, RRV
(Reliability, Resiliency, and Vulnerability), and energy scarcity index. This index
is defined in a similar way than the precipitation drought indeks from
standardized data and a given scarcity threshold (constant threshold or moving
threshold defined on calendar basis).
The result showed that solar power generation had the lowest production
in whole regions on 1982, 1997, and 2011 using moving threshold. Besides,
Hydropower generation was low during 1991 and 1996; and wind power scarcity
production was on 1996 and 2000. On constant threshold, hydropower was low
on 1989, 1992, and 2003; wind power scarcity was on 1994, 209, and 2012.
However, solar power was always below the threshold production in every winter.
Furthermore, based on the plot of scarcity indeks, on 1995 to 1997, the energy
production was lower for all sources over the whole domain. The highest demand
overload for all regions happened on 2005.
