Multi-Objective Stochastic Optimization for Determining Set-Point of Wind Farm System

Abstract: Due to the uncertainty in output power of wind farm (WF) systems, a certain reserve capacity is often required in the power system to ensure service reliability and thereby increasing the operation and investment costs for the entire system. In order to reduce this uncertainty and reserve capacity, this study proposes a multi-objective stochastic optimization model to determine the set-points of the WF system. The first objective is to maximize the set-point of the WF system, while the second objective is to m… Show more

“…That is why combining power plants that have a more flexible output, for example, gas turbine, benefiting from Plug-in Electric Vehicles (PEV) if a moderate portion of PEV owners are convinced to provide service [133] and using diesel generators in combination with other less intermittent RES can reduce output fluctuations of them [134]. In order to decrease the added reserve capacity due to the presence of wind energy, [135] proposed a multi-objective stochastic optimization to provide wind farm operators with an optimal set-point of the wind farm. In this study, the two objectives are maximising the wind farm set-point and the probability of fulfilling the determined set-point in the real-time operation, leading to the reduction of the uncertainty of the output power.…”

“…The rated power is 10 MW with a minimum set-point of 1 MW. The maximum ramp-up and ramp-down in two consecutive intervals are 2 MW [28]. As mentioned earlier in Section 3.2, the value of α, β in the objective function (6) represents the weight of each grid-code constraint in the WF operation.…”

“…Weather derivatives are used to manage the economic consequence of non-catastrophic weather events on companies' performance [1][2][3][4][5][6][7][8][9][10][11][12][13]. Given there is no standardised pricing model for weather derivatives, recent studies have developed different pricing models using underlying indices derived from climatic variables like temperature [2,4,5,8,[10][11][12][14][15][16], irradiance [17], rainfall [3,6] and wind [18][19][20][21].…”
