VARIABLE RENEWABLE ENERGY
(VRE), i.e., wind and solar photovoltaics
(PVs), is being installed in
rapidly increasing amounts around the
world. Growth in VRE is being spurred
by ambitious zero-carbon targets set
by countries and individual states
across the globe. The European Union
approved a carbon neutrality target for
2050 in 2019. Japan's newly appointed
prime minister announced the same
target in 2020, and the Chinese government
set goals to peak carbon emissions
before 2030 and become carbon
neutral by 2060.
In this article, we first present some
recent records of VRE integration
around the world. Next, we discuss the
operational challenges with the growth
of VRE including more frequently seen
zero and negative prices, curtailment,
and congestions seen in some regions
in Europe, the United States, Australia,
China, Japan, Brazil, and Chile.
Finally, a few ongoing and planned
mitigation strategies for managing the
growing shares of VRE are discussed.
Record-High Wind
and Solar Shares
The year 2020 saw a new record-high
penetration of wind and solar generation.
