With the increase of wind power capacity in
China, the situation of curtailment of wind power is getting worse. An annual
sequence production simulation model is established with maximum wind power
consumption as the objective function. The calculation of specific power grid
operation in 2013 verifies the precision of this model. The impact of different
factors on wind power accommodation as well as the impact of power grid
reserve, wind resources and load on wind power curtailment is analyzed. The
calculation results quantify the impact of different factors from power system
to the accommodation of wind power and provide reference to solving the problem
of wind power curtailment.
We demonstrate a smart optical fiber sensor unit to
realize a multi-parameter sensing, including temperature, curvature and strain
or displacement. The sensor unit is composed of a Bragg grating in graded-index
multimode fiber and a Fizeau cavity.
