TL;DR: In this paper, the performance of improved short-term wind power ramp forecasting was evaluated for the Electric Reliability Council of Texas (ERCOT) by comparing the experimental WFIP forecast to the current short term wind power forecast (STWPF).
Abstract: The variable and uncertain nature of wind generation presents a new concern to power system operators. One of the biggest concerns associated with integrating a large amount of wind power into the grid is the ability to handle large ramps in wind power output. Large ramps can significantly influence system economics and reliability, on which power system operators place primary emphasis. The Wind Forecasting Improvement Project (WFIP) was performed to improve wind power forecasts and determine the value of these improvements to grid operators. This paper evaluates the performance of improved short-term wind power ramp forecasting. The study is performed for the Electric Reliability Council of Texas (ERCOT) by comparing the experimental WFIP forecast to the current short-term wind power forecast (STWPF). Four types of significant wind power ramps are employed in the study; these are based on the power change magnitude, direction, and duration. The swinging door algorithm is adopted to extract ramp events from actual and forecasted wind power time series. The results show that the experimental short-term wind power forecasts improve the accuracy of the wind power ramp forecasting, especially during the summer.Copyright © 2014 by ASME

TL;DR: In this article, a power system is connected to a wind force power generating facility, a solar photovoltaic power generation facility and a power load load through a main bus bar and an auxiliary bus bar.
Abstract: PROBLEM TO BE SOLVED: To separate fluctuations in a load and a distributed power supply into frequency bands, enables a load following operation, and compensate a rapid load fluctuation and a power fluctuation hardly followed. SOLUTION: A power system 11 is connected to a wind force power generating facility 15, a solar photovoltaic power generating facility 16 as a natural energy power supply 10 and a power load 17 through a main bus bar 13 and an auxiliary bus bar 14. A total power calculating section 19 sums power from the natural energy power supply 10, and calculates the total power. The main bus bar 13 is connected to a power storage apparatus 22 comprising an engine power generator 21 and a secondary battery as the distributed power supply for implementing the load following operation through the auxiliary bus bar. A deviation between a load power detection value and a setting of power received by a system linking point is separated into a low frequency component and a high frequency component by a low pass filter 27. The engine power generator 21 is controlled by the low frequency component. The power storage apparatus 22 is controlled by the high frequency component. COPYRIGHT: (C)2007,JPO&INPIT

TL;DR: The reliability of a power system depends on maintaining frequency within predetermined limits around the nominal operating frequency (60 Hertz in North America) as discussed by the authors, which is a fundamental aspect of operating an electric power grid reliably.
Abstract: The reliable operation of a power system depends on maintaining frequency within predetermined limits around the nominal operating frequency (60 Hertz in North America). A fundamental aspect of operating an electric power grid reliably is that the amount of power produced at any given instant must match almost exactly the amount of power being consumed. If extra power is produced, the frequency will tend to increase. If less power is produced, the frequency will tend to decrease. The frequency of the interconnected grid is mostly controlled by adjusting the output of generators in order to maintain a balance between generation and load. This balancing and frequency control occur over a continuum of time, using different resources that fall into the categories of primary, secondary, or tertiary controls.

TL;DR: This paper presents two active power control schemes that are developed based on adaptive pole placement control and fuzzy gain-scheduled proportional-integral control approaches and demonstrates that the mentioned schemes are able to tolerate probable occurrence of sudden imbalance between generation and load due to relevant faults/failures in the wind farm or electric grid.
