The increased integration of wind generation via high power converters imposses numerous gauntlet to the management and control of modern power systems. One of them is caused by the decoupling effect between the power sources from the AC grid. It negatively impacts the system frequency response of modern power systems. This paper proposes a controller to enable the primary frequency regulation on...
This paper presents a simple controller to enable the inertial response of utility-scale battery energy storage system (BESS). Details of the BESS modeling are presented in this paper. The main contribution of this paper is to demonstrate that inertial controller in BESS help to reduce change to the rate of change of frequency (RoCoF), providing frequency support and improving the system frequency...
The importance of Energy Storages System (ESS) without a doubt is started to compete for the importance of Renewable Energy System (RES) nowadays and in the near future. ESS such as grid-scale batteries has the advantage of storing energy and provides many other services and functionalities to the power system. This paper investigates the effect of installing Battery Energy Storage System (BESS) on...
One of the main challenges in future power systems is the enormous integration of generation units using high power converters as interface, it decouples new power sources from the AC power grid, incapacitating a natural frequency response. This situation decreases the total system inertia affecting the ability of power system to overcome system frequency's disturbances. This paper evaluates two inertial...
One of the challenges in future energy systems is the massive use of high power converters that decouple new energy sources from the AC power grid, disabling natural frequency response. This situation decreases the total system inertia affecting the ability of power system to overcome system frequency's disturbances. It has been established by the wind power industry a controller to enable inertial...
<?Pub Dtl?>Controlled islanding is an active and effective way of avoiding catastrophic wide area blackouts. It is usually considered as a constrained combinatorial optimization problem. However, the combinatorial explosion of the solution space that occurs for large power systems increases the complexity of solving it. This paper proposes a two-step controlled islanding algorithm that uses...
An evolutionary computation technique is used to minimize the active power losses, subjected to voltage constraints. The formulation is proved in two power systems, controlling variables such as generation voltages, taps position, and shunt elements, showing a reduction not only on power system losses but also resulting in a power generation decrement. These results are used to analyze the impact...
