- Integration of renewable energy generating units into thermal generation system is an alternative in supplying electrical energy to fulfill demand needs. However, including renewable energy technology which is intermittent such as solar and wind power is faced on many technical and economic impacts. One of the problems is how to optimize the generation in order to minimize operation cost while maximizing utilisation of renewable energy resource. This theses proposes a method on short term scheduling of hybrid generation system consisting of thermal units, photovoltaic systems, windparks, and battery as electrical storage. The objective is to minimize generation cost i.e fuel cost and start-up cost while satisfying all system, thermal unit, renewable unit, and battery constraints with considering variability of load demand and renewable energy. Optimal scheduling of this hybrid thermal-renewable-battery system is formulated in Mix Integer Programming (MIP) model and solved by Tomlab CPLEX based optimization software. Simulation on test system using 10 thermal generation units show that this methode can effectively solve scheduling problem. Comparing with other methods (LR, GA, and LRGA) using identic test system and scenario, scheduling with this method results on lower generation cost by 0.9%.
