PV Plant Influence on Distribution Grid in Terms of Power Quality Considering Hosting Capacity of the Grid

Abstract

Photovoltaic plants penetrate rapidly in distribution grid. Problems with their integration in distribution grid can exist in terms of load flow, protection settings, power quality, etc. This chapter analyzes influence of photovoltaic plants connection in distribution grid (0.4 and 10 kV voltage level) on power quality. The main focus will be on influence of photovoltaic plant connection point on distribution grid (hosting capacity-strength of the grid) in terms of power quality. Norms and regulations about influence of photovoltaic plants on distribution grid in terms of power quality will be analyzed. Influence of photovoltaic plants on distribution grid in theoretical aspects will be presented. Several case studies then will be described. Those case studies present different connection points of photovoltaic plants on distribution grid. Comparison of theoretical assumptions and real case studies will be compared. Some observations of real case studies and their impact on theoretical aspects, norms, and regulations about photovoltaic plant influence on distribution grid will be introduced.

“…Com o aumento de SFCR surgem também questionamentos sobre os impactos da conexão desses sistemas na rede elétrica. A influência da inserção dos SFCR pode causar problemas para as concessionárias e clientes, provenientes de distúrbios na rede, principalmente quando os parâmetros associados a QEE estão fora do estabelecido pelo Procedimento de Distribuição de Energia Elétrica no Sistema Nacional (PRODIST) (Ramljak;Bago, 2018;Nunes, 2017).…”
