7. Conclusions

In this paper, the load forecasting and wind speed fore-

casting are adapted in the power system which involves

wind power system. The case study that implemented in

the simulation consists of 15% wind power system in total

of grid power. The load distribution and re-distribution

between different power systems gave the optimization of

the generated power. Thus, the influence from the inter-

mediate behavior of the wind power systems is minimized

through good estimation of the 24 hrs ahead wind and

load forecasting. The simulation results show the behavior

of the steam and gas turbine while they provide baseload,

and other systems in intermediate and peak loads. The

achievement of optimization has been successful since the

grid previously prepared for distribution load, and the

correction due to errors in forecasting take place without

disturbance to the baseload or influence to the balance

between available capacity and load demands.

This work may be extended to include other renewable

power systems such as solar power system. Also, it may

adapt weather forecast directly from the forecast centers.
