“…This results in a reduction of system inertia and spinning reserve. Moreover, RESs typically do not have to provide frequency regulation or other control services such as voltage support [1]. The transmission system operators (TSOs) are tackling the problem by updating grid codes to include regulation duties and control services contribution from wind farms and photovoltaic plants.…”

Frequency stability in power systems is a key driver for the maintenance of supply quality. Thermal loads, if properly managed, can play an important role in providing support to the frequency regulation. In this framework, the paper presents a control strategy to enable a load aggregator to manage a set of building cooling systems to contribute both to primary and secondary regulation. The proposed strategy uses the Model Predictive Control approach. Frequency support is provided without compromising the natural mission of the controlled loads, i.e., the end-user thermal comfort. The introduced method is tested by means of software-in-the-loop simulation studies. The implemented testing framework emulates real-time operation of a building aggregate within a benchmark network with high penetration of wind generation. Results show the ability of the control algorithm to optimally coordinate the contribution of thermal loads both to primary and secondary frequency regulation.

“…Several control schemes for smoothing the output power of a WTG by controlling the pitch angle have been reported [5][6][7][8][9][10]. However, these methods substantially decrease the captured power from the incoming wind power, and control schemes that entail releasing the kinetic energy stored in the rotating masses of WTG blade and gearbox have been proposed [11][12][13].…”

Coordinated Frequency Stabilization of Wind Turbine Generators and Energy Storage in Microgrids with High Wind Power Penetration

et al. 2019

This paper proposes a coordinated control scheme for wind turbine generators (WTGs) and energy storage in microgrids with high wind power penetration. The proposed scheme aimed to reduce the system frequency deviation caused by variations in wind power and loads. To stabilize the frequency, the WTG and energy storage system (ESS) are used for kinetic energy generation and electrical energy storage, respectively. When the WTG contributes excessively to frequency stabilization in the microgrid with a high wind power penetration, the system frequency may fluctuate considerably. Thus, it is necessary to adjust the contribution of a WTG and to share it with other sources. To achieve our objective, we proposed a coordinated control scheme between the WTG and ESS that shares their releasable and absorbable energies. The coordinated control consistently calculated the releasable and absorbable energies of the WTG and ESS and determined weight factors related to the energy ratios. Accordingly, the weight factors improved the ability of providing supporting frequency stabilization of the WTG and ESS by increasing the stored energy utilization. The performance of the scheme was investigated using MATLAB Simulink Electrical. The results show that the proposed coordinated control successfully stabilized the system frequency by calculating the appropriate contributions required from the WTG and ESS.

This article presents a methodology to help in the definition of the optimal design of power generation systems. The innovative element is the integration of requirements on dynamic performance into the system design procedure. Operational flexibility is an increasingly important specification of power systems for base-and part-load operation. Thus, it is crucial to discard, in an early phase of the design process, plant configurations which feature unacceptable dynamic performance. The test case is the preliminary design of an off-grid power plant serving an off-shore platform where one of the three gas turbines is combined with an organic Rankine cycle turbogenerator to increase the overall energy efficiency. At the core of the procedure is a stationary model, capable of performing the on-design thermodynamic cycle calculation, and the design of the components of the system. The results of these simulations are used within the framework of a multi-objective optimization procedure to identify a number of equally optimal system configurations. A dynamic model of each of these systems is automatically parameterized, by inheriting its parameters values from the design model. Dynamic simulations allow then to discriminate among the initial set of solutions, thus providing the designs that also comply with dynamic requirements.
