It is well known fact that solar flares are efficient particle accelerators - even several concurrent acceleration processes can take place in a single flaring volume. Using hybrid and particle simulations we study some of them, namely the direct acceleration in the current sheet torn during the magnetic reconnection, the acceleration in collapsing magnetic traps formed inside the cusp structure, and pinch-effects in non-equilibrium plasmoids newly created by the reconnection process. In order to relate our models more directly to the real world we not only calculate the dynamics of electron distribution functions but we extent our results to the form comparable with observations. As accelerated particles in the solar atmosphere manifest themselves most remarkably by the radio and X-ray emissions the final outputs of our modelling are radio and X-ray spectra and their dynamics as well as spatial structures of X-ray and radio sources. The obtained results are, of course, sensitive to the parameters of the used flare model. Conversely, fitting the observed and the modelled data provides us with the diagnostic tool for investigation of conditions under which the acceleration in the solar flares proceeds.
