Generation expansion planning including the renewable energy sources

The authors study the long-term competitiveness of introducing renewable energy sources alongside the conventional generating units in a generation expansion plan by linking a short-term study and a long-term planning model. The short-term study is an extensive examination of the different combinations of the renewable energy sources which can operate with the conventional generating system for different objectives. These objectives are varied between two general strategies: the fuel-saver strategy and the peak-shaving strategy. In long-term planning, these combinations are considered as decision variables. For this purpose, a long-term generation expansion planning model is used to decide which strategy can be used and the capacity as well as the time of addition.<>
