“…The penalty coefficients take a value from 0 to 1 as shown in Equation (2). Equation (3) pertains to relationship for power balance; when determining P ESS in (t) and P ESS out (t), priority is given to meeting the constraint prohibiting simultaneous charge/discharge in Equation (4) as well as the constraints prohibiting discharge of uncharged battery and charge of fully charged battery in Equations (5) and (6). Now, the variable M in Equations (5) and (6) is to a sufficiently big value that cannot be taken by decision variables so as to express whether charge/discharge is possible.…”

“…2,3 A number of methods for fluctuation suppression control of wind power output have been already studied, including control using storage batteries and other energy storage systems (ESS), and turbine pitch angle control. [4][5][6][7][8] Those studies, however, focus on so called short-period fluctuations that affect system frequency, while no consideration is given to suppression of fluctuations with a period of several hours, such as economical load dispatch, caused by ramp events that are anticipated with massive introduction of wind power generation.…”

Recently, wind power generation are installed as a countermeasure for the environmental issue in Japan. However, wind power generation output is fluctuated due to wind condition. Moreover, it is some negative impact for system operation such as the economic load dispatching control and the load frequency control. In Japan, NEDO has started the project as a countermeasure for massive penetration of wind power generation in 2014, called "R&D Project on Grid Integration of Variable Renewable Energy." In this paper, we proposed the output fluctuation suppression control method of wind power generation using the battery and forecast data of wind generation output. Specifically, the target value of wind power generation output is calculated to decrease the deviation output from fluctuation suppression code for ramp event using deterministic optimization method. The effectiveness of proposed method is evaluated through the computational simulation using forecast data and actual wind power generation output in Tohoku area.

Renewable energy such as wind generation is a countermeasure against global warming and fossil-energy resource depletion. However, wind-farm (WF) output fluctuates because of unstable wind conditions and the occurrence of long-term fluctuations, which are called ramp events. WF power generation operator needs to observe the grid code (GC) by controlling wind generators themselves or adjusting a WF output with the energy-storage system (ESS). Accordingly, scheduling the operation of WF with ESS and WF output forecast is necessary. Scheduled operation has two parts: scheduling of generation plans (SGP) and operating WF (OWF) outputs with the charge/discharge of ESS. This paper proposes the scheduling method, which can control ramp events and satisfy GC formulation such as mixed integer liner programming in the SGP part, and the balancing method, which can reduce the imbalance energy due to control delay of ESS in the OWF part. We also evaluate these methods by annual numerical simulation. We further confirm the validity and effectiveness of the proposed method, as well as approximate its battery capacity requirement.

“…As regards previous research in WF output control, batterybased control, [6][7][8][9] pitch angle control of wind turbines, [10][11][12][13][14] and other methods were proposed. However, some other control methods are needed to deal with slow fluctuations with a period of several ten minutes in order to solve the issues of demand-supply operation.…”

Recently, the penetration of wind farm (WF) has been increasing because of the global warming and the lack of the fossil energy resource. However, WF output fluctuate due to the weather and the seasonality. Specially, the long-term fluctuation is called "Ramp event." It's difficult for WF output to dispatch to the power grid without controlling the ramp events. This article proposes the method of scheduled operation to mitigate the ramp events and reduce the imbalance energy with the stochastic programming. In this method, it's necessary to use the WF output scenarios. However, there has never been studied the method of generating scenarios with the temporal correlation so far. Therefore, we propose the production method of generating scenarios considering the temporal correlation with copula. Finally, this article shows the validity and the effectiveness of these methods through computational simulations using the integrated WF data of Tohoku area.
