Due to uncontrolled natural variables such as wind speed, the correlation between the renewable energy production and the demand is strenuous. In order to make the renewable enrgy system effective the energy storage systems are utilized employing the, control systems for the enegy in the battery and power. In addition, the rapidly changing wind speed, particularly in wind turbines, causes variations in the power obtained from wind causing instability at a higher power levels. The system engaged in storing energy is employed to reduce fluctuations in power and to maintain stability of power systems. In this study, a wind turbine system integrated with energy storage system was created. This system is modeled and tested in MATLAB / Simulink. The results obtained evinces that the proposed system reduces power fluctuations and succeeds in meeting load demand.

This paper deals with the modelling and control for wind turbine combined with a battery energy storage system (WT/BESS). A proportional-integral (PI) controller of pitch angle is applied to adjust the output power of WT, and a method for battery scheduling is presented for maintaining the state of charging (SOC) of BESS. When the battery level is below the lower limit, we increase the expected output power of wind turbine through raising the operation point to charge the battery. Considering the effect of charging/discharging, a switched linear system model with two equilibriums is presented firstly for such WT/BESS system. The region stability is analyzed and an approach for estimating the corresponding stable region is also given. The effectiveness of the proposed results is demonstrated by a numerical example.

<span style="font-size: 9pt; font-family: 'Times New Roman', serif;">Renewable Energy (RE) penetration is a new phenomenon in power systems. In the advent of high penetration of RE in the systems, several issues have to be addressed especially when it involves the stability and flexibility of the power systems. Battery Energy Storage System (BESS) has gained popularity due to its capability to store energy and to serve multiple purposes in solving various power system concerns. Additionally, several BESS can be combined to operate as Virtual Power Plant (VPP). This study will involve the design and implementation of BESS for five potential customer sites for the demonstration project and to be possibly integrated into one VPP system.

Recently, the interest in utilizing energy storage systems (ESSs), particularly batteries, has increased. ESSs are employed for several enhancement tasks in power systems on both the operation and planning scales. On the operation side, ESSs play a main role in offering several ancillary services. In the context of planning, ESSs are used for asset upgrade deferral among other grid applications. This work employs a battery energy storage system (BESS) to minimize the electricity bill charges associated with global adjustment for large consumers in the jurisdiction of Ontario, Canada. An optimization formulation for sizing and scheduling the BESS, to minimize the utility charges and gain profits from other revenue streams, such as energy price arbitrage (EPA), was developed and implemented. The results show the economic feasibility of the developed algorithm to minimize the annual bills of real customers and gain profits. A sensitivity analysis was also carried out to show the potential of the proposed method in providing significant benefits and gains for customers.

To harness the energy contained in such unconventional sources as winds, tides, and sunlight, a power system must incorporate an energy storage device to act as a buffer between the source and the load. Since the size of the energy storage device depends upon the relative timing of the availability of energy and the load demand, a system simulation is a logical approach to the study and design of power systems using these unconventional en ergy sources. GPSS is presented as an excellent simula tion vehicle. The physical properties to be simulated are discussed and the resulting GPSS programs are presented. Some proposed applications for these power systems are presented.
