“…Já os sistemas propostos por [8]- [9] conectam o banco de baterias ao barramento CC através de um conversor CC-CC bidirecional Buck/Boost. Destaca-se ainda que os sistemas propostos por [4]- [6] e [9] não utilizam conversor dedicado ao sistema fotovoltaico, enquanto que [7]- [8] fazem uso de um conversor Boost conectado ao sistema fotovoltaico para interface entre o PV e o barramento CC do sistema. Os sistemas apresentados em [4]- [9] não permitem a conexão de cargas trifásicas e/ou monofásicas de forma simultânea no lado CA (não possuem o condutor de neutro).…”

Este trabalho apresenta a aplicação do conversor Dual Active Half-Bridge (DAHB) no gerenciamento de múltiplas fontes em sistemas de geração de energia. O sistema emprega uma geração fotovoltaica (PV), um banco de baterias para armazenamento (ESS) do excedente não consumido, associados a uma geração CA composta de gerador de indução auto excitado (GIAE) e um compensador síncrono estático de distribuição (DSTATCOM). Neste artigo dá-se ênfase ao gerenciamento da energia excedente, gerada pelo GIAE, não consumida pelas cargas. Para o funcionamento do conversor DAHB emprega-se a modulação PWM simétrica, e, com base nesta modulação, desenvolve-se a modelagem matemática do conversor DAHB. O projeto dos controladores é realizado com base na modelagem desenvolvida. Por fim, resultados de simulação e experimentais validam o conversor DAHB e os controladores projetados.

“…Several research works have been carried out in regulating voltage and frequency to enhance the damping capability of the power system. Authors in [22]- [24] demonstrated that STATCOM with BESS can improve the damping of voltage and frequency or power. However, the studies either did not consider battery SOC or considered as a constant value which is not considered in a real power system.…”

“…However, the studies either did not consider battery SOC or considered as a constant value which is not considered in a real power system. Moreover, only the conventional PI is applied to regulate BESS [23], [24] and also the proposed BESS control is prone to rapid charging/discharging as no deadband is employed in the design [22]- [24]. Active or reactive power priority controlled BESS in an isolated power system is investigated in [25] for regulating frequency or voltage, one at a time.…”

This paper investigates the enactment of Battery Energy Storage System (BESS) and Static Compensator (STATCOM) in enhancing large-scale power system transient voltage and frequency stability, and improving power export capacity within two interconnected power systems. A PI-lead and lead-lag controlled BESS is proposed for multimachine power system to provide simultaneous voltage and frequency regulation within the defined battery state-of-charge (SOC) ranges and an equivalent Finnish transmission grid is used to evaluate the system performance. According to Australian National Electricity Market (NEM) grid requirements, the performances of the proposed control schemes are compared with conventional PI controlled BESS and STATCOM under multiple temporary and permanent fault conditions. In addition, two adjacent disturbance events are also applied to evaluate system performance with BESS and STATCOM. Through simulation results, it is shown that when there is a 44% increase in power export and the STATCOM fails, incorporating BESS improves the performance and justifies the novelty of this study. Moreover, the proposed lead-lag controlled BESS manifests better transient performance than BESS with PI-lead and traditional PI controller, in the event of divergent temporary and permanent faults.

“…The authors used NSGA-II for optimizing the multi-objective problem. Jena et al [29] used a Fuzzy Controlled STATCOM to improve the voltage and frequency stabilization in a micro hydro-PV-battery hybrid system. Jurasz et al [30] maximized the energy and controlled the variability of run-of-river PV hybrid power plants by using mixed integer mathematical programming.…”

This paper presents the sizing of run-of-river small hydro-PV hybrid power system using the Non-dominated Sorting Genetic Algorithm (NSGA-II). The two objective functions are the total generated energy and the energy production cost of hybrid system. The total energy has been maximized whereas the energy production cost of hybrid system has been minimized. The nominal turbine flow rate ( ), the number of hydropower units ( ), and the number of PV modules () are considered as decision variables in this problem. The Yeripao site in Benin has been considered as case study. The optimal solutions converge to Pareto front which represent the best trade-offs between total generated energy and energy production cost. The results have shown that energy production cost increases with the total generated energy. Thus, minimizing the energy production cost is contradictory with maximizing the total generated energy. Moreover, the sensitivities analysis of and on the total generated energy and on energy production cost have been conducted in this study. It is relevant to note that the optimal solutions are grouped into four categories according to = , , . For each category, the total generated energies, energy production costs and cost per kWh increase with the . For = the lowest values of energy production costs, total generated energies and costs per kWh have been recorded. Moreover, = match with the solutions that present the highest total generated energies and costs. The lowest overall cost per kWh is € 0.363/kWh. The conducted study can be applied to other sites by using their hydro and solar resources characteristics.
