Power generation maximization of distributed photovoltaic systems using dynamic topology reconfiguration

Protection and Control of Modern Power Systems

Table 1 Summary of dynamic topology reconfiguration solutions

Ref	Reconfiguration solution	Types of mismatch conditions	Configurations	Remarks
[14,15,16,17]	Dynamic PV array	Partial shading	TCT	Require a large number of switches: the number of switches depends on the number of modules
[17]	two-step GA-based reconfiguration	Partial shading	TCT	Require a large number of switches: the number of switches depends on the number of modules
[18]	Adaptive bank	Partial shading	TCT	Limit the number of switches: the number of switches depends on the number of PV strings Cannot work well in certain partial shading patterns
[19]	Adaptive bank	Partial shading	SP	Limit the number of switches: the number of switches depends on the number of PV strings Cannot work well in certain partial shading patterns
[20]	Adaptive utility inter- active system	Partial shading	SP	Require a large number of switches: the number of switches depends on the number of modules
[21]	Optimized-String DPVA	Partial shading	SP and TCT	Require a large number of switches: the number of switches depends on the number of modules
This work	Dynamic PV array	partial shading, module failure	SP and TCT	Limit the number of switches: the number of switches depends on the number of PV strings and inverters
