To accommodate the increasing wind energy with stochastic nature becomes a major issue on power system reliability. This paper proposes a methodology to characterize the spatiotemporal correlation of multiple wind farms. First, a hierarchical clustering method based on self-organizing maps is adopted to categorize the similar output patterns of several wind farms into joint states. Then the hidden...
An optimal wind power curtailment strategy considering operation capacity credit is proposed in this paper to minimize the uncertain wind power curtailment and minimize the system operation cost. The relevant definitions in capacity credit assessment are applied in the power system operation situation. Based on operation capacity credit prediction, the optimal operation control strategy is defined...
<?Pub Dtl?>The Danish power system has a large penetration of wind power. The wind fluctuation causes a high variation in the power generation, which must be balanced by other sources. The battery storage-based Plug-In Electric Vehicles (PEVs) may be a possible solution to balance the wind power variations in the power systems with high wind power penetrations. In this paper, the integration...
This paper proposes an optimal power flow (OPF) method taking into account small signal stability as additional constraints. Particle swarm optimization (PSO) algorithm is adopted to realize the OPF process. The method is programmed in MATLAB and implemented to a nine-bus test power system which has large-scale wind power integration. The results show the ability of the proposed method to find optimal...
