Design of a Power System Stabilizer for a Hydro-Power Based on a Nonlinear Sliding-mode Controller

The power plants commitment is an optimization problem for units in where the objective is tominimize the production costs and satisfy the specified power supply. In this paper, a two-stageoptimization method is proposed to consider the uncertainties of the wind power plant associatedwith the storage of pump storage power plant. The estimation of the accurate size of output powerof these power plants is more difficult due to the variable nature of wind power plants. Theproposed methods optimizes the network reliability to plan the partnership units using robustoptimization. Provide a robust method for the circuit to put wind power with pumped storage ofwater in the power market . new renewable energies are increasingly coming to power system aremaintain reliability in un certain how to boost confidence in renewable energy has causedchallenges in the operation of the power system . one of these new energies wined energy is thefundamental problem is the wind energy is the energy of natural changes too in common with thewith the power circuit manufacturers to put the basis of un optimization problem where the goalis to minimize cost of production units and satisfy the supply constraint is time . this paper proposesa two stage optimization method for taking into account the un certainties of the wind power plantwith storage of pumped storage power plant is provided . because of the variable nature of windpower plants is more difficult to estimate the exact size of the output power as well In the initialstudy of this paper, a six-bus network is assumed consisted of four fossil fuel generators, a windgenerator and a generator of water storage pumps and this network includes 7 lines of presumedlinks. Then, the overall results will be simulated and studied in a six-bus network of one hundredand eighteen, and one hundred and eighty-six of connection lines and thirty-three heating plantsby adding a wind generator and a water storage pump generator.
