INTEGRATION OF VARIABLE ENERGY SOURCES IN ENERGY SYSTEMS
Journal of Engineering Science, 2022 The main global concern in the energy sector is the substitution of fossil fuels and the mitigation of climate change – the transition to the carbon neutrality of the economy. For the power sector, the main solution for this transition is to use hydro, wind and solar energy sources, which have a high energy potential, including in the Republic of ...

Linear energy-preserving integrators for Poisson systems [PDF]
BIT Numerical Mathematics, 2011 The authors introduce a new class of energy conserving integrators in order to solve initial value problems for non-canonical Hamiltonian systems. In contrast to similar integrators, these are invariant to linear transformations. They also conserve quadratic Casimir functions and they are of arbitrarily order of accuracy.
