Abstract—This paper proposes an adaptive optimal policy for hourly operation of an energy storage system (ESS) in a gridconnected wind power company. The purpose is to time shift wind energy to maximize the expected daily profit following uncertainties in wind generation and electricity price. A stochastic dynamic programming (SDP) framework is adopted to formulate this problem, and an objective function approximation method is applied to improve the SDP computational efficiency. Case studies on the Electric Reliability Council of Texas demonstrate that the resultant profits from SDP-based operation policy are considerably higher than those from deterministic policy, and comparable to those from the perfect information model. It is concluded that the presented SDP approach can provide operation policy highly adaptive to uncertainties arising from wind and price. The proposed framework can help the wind company optimally manage its generation with ESS.

ABSTRACT Due to the power-grid low-order harmonic voltage and the nonlinearity of power electronic devices, the grid-connected converter of wind power generation system produces grid-connected harmonic current. In order to improve the output power quality of full-power grid-connected converter of wind power generation system, based on the detailed analysis of the harmonic mathematical model of grid-side converter, a cross-coupling control strategy for suppressing the low-order harmonic current components is proposed in this paper. In this control strategy, the DC component of each grid-connected harmonic current is detected in the multi-synchronous rotating coordinate system, and the current cross-coupling control method is adopted to realize the accurate control of each harmonic current. The harmonic current cross-coupling controller is analyzed and designed in detail. The proposed control strategy takes into account the cross-coupling effect of each harmonic current, which can effectively reduce the interaction between each harmonic current and the fundamental current, and improve the stability of the system. Simulation and experimental test verify the correctness and feasibility of the proposed control strategy.

Abstract——Injection of the wind power into an electric grid affects the power quality. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation and these are measured according to national/international guidelines. The paper study demonstrates the power quality problem due to installation of wind turbine with the grid. In this proposed scheme STATic COMpensator (STATCOM) is connected at a point of common coupling with a battery energy storage system (BESS) to mitigate the power quality issues. The battery energy storage is integrated to sustain the real power source under fluctuating wind power. The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set. The effectiveness of the proposed scheme relives the main supply source from the reactive power demand of the load and the induction generator. The development of the grid co-ordination rule and the scheme for improvement in power quality norms as per IEC-standard on the grid has been presented.

针对风电并网的电压源换流器高压直流输电(VSC-HVDC)系统的传统双闭环控制策略存在控制结构复杂、PI参数较多且难以整定、响应速度慢等问题，提出适用于风电并网的VSC-HVDC系统模型预测控制策略。为了提高风电场母线交流电压的控制精度，风电场侧换流器(WFVSC)采用基于优化模型预测的定交流电压控制，提出滞后补偿两步预测法，并将模型预测控制与脉宽调制(PWM)技术相结合，求取2个控制周期内调制波的最优解，然后经过调制单元生成开关信号作用于WFVSC。网侧换流器(GSVSC)采用有限控制集模型预测功率控制，基于GSVSC的离散数学模型，利用代价函数遍历寻优找出使代价函数最小的开关状态组合作用于GSVSC。基于所提模型预测控制的VSC-HVDC系统具有良好的稳态性能、动态性能和故障恢复性能，能为风电场提供稳定的交流电压。仿真结果验证了所提控制策略的可行性和有效性。
