The paper presents a new wind power generation planning framework by considering the reactive power capabilities of generators. The motivation is to maximize the utilization of renewable power hosting capacity without violating the security constraints of distribution networks. The objective is to maximize the net present value of the investment considering the cost of grid energy transaction, initial...
To meet the increasing electricity demand in the island of Indonesia, especially in areas that are lack access of electricity, it would be beneficial for these these islands to produce electricity using local potential renewable energy sources. In this study, Papua Province, the eastern region of Indonesia with 28 Districts, where 2,114 villages do not have electricity access was taken as the region...
This paper presents the influence of non-conventional sources like central station solar photovoltaic model and wind plant model in multi-machine power system for transient stability. Modified four-generator system is studied by replacing one of the conventional synchronous generators with solar photovoltaic and wind generator model. The performance is compared with the classical four-generator system...
The imbalance between consumption and demand, caused by the integration of intermittent renewable energy sources (ReS), increases the need of Ancillary Services (AS) for frequency support (FS). This imbalance is still regulated with the help of conventional generation, by procuring reserves for frequency support. However, as the aim is to increase the share of RES in electricity generation, they would...
With more wind power integrating into power grid, a lot of issues are caused by its uncertainty and variability. In order to analysis wind characters, this paper proposes a method to model wind power. This method bases on stochastic Burgers equation. It turns wind power model from three dimension to one dimension in order to simplify the physical model and generate more wind speed data to improve...
The foreseen high penetration levels of wind energy will have serious implications on frequency stability, hence developed control methods of wind turbine and alternative technologies including energy storage should enable the provision of frequency support by wind power. Active research is ongoing to investigate the possibility of collecting and transmitting offshore wind power through low frequency...
Large-scale integration of renewable resources for power generation is a propitious mode to mitigate the impact of human activities in order to reach an environmentally and sustainable way of life. However, uncontrollability and variability of renewable resources is an important barrier that could be overcome by incorporating energy storage systems (ESSs). Among ESSs technologies, Vanadium Redox Battery...
Feasibility study on implementing wind energy harvesting system on moving train is discussed in this study. Wind turbines installation over the train roof is suggested and tested from different aspects. Practical aspects of wind energy utilization are discussed and challenges are highlighted. Calculations of wind power generation for wagon roof mounted turbine are provided and air drag of turbine...
Vast increase of renewable energy resources' (RER) share in total electricity production have led to evolving studies regarding different aspects of renewables integration. Other than their effects on network, the electricity markets are also affected by uncertain behavior of RERs in the market place. Hence, new approaches for market clearing are investigated. One of the possible solutions is the...
Power output of wind generators is always associated with some uncertainties due to wind speed and other weather parameters alteration, and precise short-term forecasts are essential for their efficient operation. This can efficiently support transmission and distribution system operators and schedulers to improve the power network control and management. In this paper, we propose a double stage hierarchical...
The objective of the proposed scheme is to extract the maximum power at different wind turbine speed. In order to achieve this, MPPT controller is implemented on the rectifier side for the extraction of maximum power. On the inverter side normal closed loop PWM control is carried out. MPPT controller is implemented using fuzzy logic control technique. The fuzzy controller's role here is to track the...
Wind power generation and Solar PV installations continues to grow and are the two key contributors to the large scale variable power generation mix. Utility transmission system operators impose stringent grid codes internationally. Grid code regulations are defined by system operators to outline the rights and responsibilities of all the generators and loads that are connected to the transmission/distribution...
These days the consumption of fossil fuel is increasing substantially and the major proportion of it is consumed by transportation sector. So, electrification of vehicles is one way to minimize their dependence on fossil fuels which also plays a significant role in reducing the greenhouse effect. However, vehicles transformation enhances the electric load which has a significant impact on current...
This paper presents a probabilistic interval optimization (PIO) model for evaluating the problem of optimal power flow considering wind power integrated (OPFWP). In PIO model, the wind power is deemed as a probability interval variable to assess its profit and risk simultaneously. To be precise, the profit is manifested by the net decrease of generation cost between the same power system with and...
Along with the rapid development of wind power generation technology, numerous of wind generators will connect into distribution network. When the wind power is equivalent to a part of the comprehensive load of the distribution network, traditional load model is not appropriate for load characteristics any more. This paper raises a new method about generalized load model, which is to add an induction...
This paper introduces two novel metrics to judge the capability and influence of wind power to provide virtual inertia response (i.e. frequency support). The first metric considers the generation unit (i.e. wind turbine generator (WTG)/wind farm (WF) vs. synchronous generator). This metric is applied to compare between three different methods of provision of frequency support. The second metric assess...
The intermittent and uncertainty nature of variable resources rises the need to investigate the effect of the technical operation aspects of power system operation and transmission lines constrains, on estimating the penetration level of variable resources that enhances the economic and operation aspects of power system. The Incorporation of these resources into systems rises the need to evaluate...
The integration of wind power into power systems has been gaining momentum in the global energy industry due to its environmental benefits and abundance of supply. However, the natural intermittent and non-dispatchable features of wind negatively impact the system's frequency regulation capability. Wind power not only injects additional fluctuations to the already variable nature of frequency deviation,...

We present a model for finding the optimal investment strategy for installing TCSC devices on a transmission network while considering the wind generation and load uncertainties. The proposed TCSC location-allocation problem is a non-linear non-convex mathematical program. We use the general linearization technique to convexify the polynomial constraints. To address the uncertainty of wind power and...
