This paper presents the analysis of a distribution system subject to reconfiguration with high wind penetration over a period of 24 hours. In order to meet this objective, the reconfiguration problem is solved through mixed integer linear programming considering the stochasticity of the variables, where the balance between load and generation has to be satisfied at the lowest cost in each period....
Wind power penetration in power systems is significantly increasing over the years. Wind generation is highly random and a significant change in wind power within a short timeframe forms a wind ramp event. These events can create severe generation-demand imbalance and cause damage to the wind turbines due to extreme stresses. Therefore, prediction of wind ramp events is essential for system operators...
Wind energy has been playing a critical role in modern electric power system due to the fact that wind is free of cost and environment-friendly. However the inherent intermittency of wind has complicated system operation such as optimal power flow (OPF). In this paper, the authors present a stochastic OPF model integrated with wind power (WOPF). Since WOPF is a highly non-linear and non-convex problem,...
The prospects of Electric Vehicles (EVs) in providing clean transportation and supporting renewable electricity is widely discussed in sustainable energy forums worldwide. The battery storage of EVs could be used to address the variability and unpredictability of electricity produced from renewable energy sources like wind in power systems. The EV batteries could be used to charge during periods of...
Due to the variability of wind power, it is imperative to accurately and timely forecast wind generation to enhance the flexibility and reliability of the operation and control of real-time power systems. Special events such as ramps and spikes are hard to predict with traditional methods using solely recently measured data. In this paper, a new Gaussian Process model with hybrid training data taken...
In this paper a novel approach is proposed to coordinate wind generators and battery energy storage systems (BESS) to provide both energy balancing and frequency regulation services in electricity markets. A robust optimization based model predictive control (RMPC) scheme is developed to determine the optimal bidding strategy for wind and storage, under uncertainty due to electricity price forecast...
Inertia issues due to increased use of modern wind turbines (WTs) have gained increased attention during the last years, especially in isolated power systems with limited frequency control capabilities. Therefore, different control strategies to allow inertial response from WTs have been proposed, either by considering deloaded operation or by using part of the kinetic energy stored in the blades...
In this paper, a model is presented to solve the problem of combined heat and power (CHP) dispatch. The system under consideration consists of both thermal generators and wind turbines. The wind power is a random variable following the Beta distribution, which is mainly used for the short-term forecasting. In the proposed model, the probability of wind power is included in the constraint set. A computer...
This paper describes the latest generic wind turbine generator models of types 3 and 4 developed for implementation in the Western Electricity Coordinating Council (WECC) base cases.
Participation of wind energy along with conventional fuel sources in power generation is progressively rising in many countries. Due to continuous development of large-scale wind farms, some synchronous generators are being economically displaced from generation schedule. Modern wind turbine generators do not generally provide frequency control support after a disturbance, while during a fault they...
In recent years wind power integration has substantially increased in southern states of Australia. At present South Australia has the highest wind generation capacity of any region across the country. This large capacity penetration would likely displace existing synchronous generation fleet. These wind generators have neither enough inertia response nor governor support to control major frequency...
The rapid integration of wind power has begun to impact overall power system control, and particularly frequency control. On the other hand, power system sensor and measurement technologies have shown great improvement during the last decade. These technologies could allow for greater use of advanced control techniques based on wide-area measurement signals to mitigate the challenges related to wind...
Due to its intermittent nature, high wind penetration requires more flexibility in the electric power grid to provide the balance. Large scale energy storage is one such option that allows the intermittency to be absorbed in real time. Two types of large scale energy storage technologies including Sodium Sulpher (NaS) battery and compressed air energy storage (CAES) are studied in this paper. In this...
