The continuous fluctuations in oil prices together with the recent nuclear disaster in Japan ha at alternatives to cope with the future energy demands. Such disasters will to give a valid input by investing in a grid connected renewable source of energy. Such sources of energy, which are clearly on the increase, are also creating an ever increasing need for ensuring stability and this has been controlled to some extent wi the drive towards self consumption. All this is creating a higher interest and scope of having some sort of battery energy storage. In this paper, the results presented at the last IRES, will first of all be extended to analyse the effects of energy mea taken on isolated small grids such as Malta with particular focus on the effect of further photovoltaic penetration.
