AI Customer ServiceThe goal of this research is to assess the importance of inverter design in battery energy storage systems (BESSs). For different designs, the trade-offs between different objectives are studied: voltage regulation at the in-house connection terminals, total peak power reduction and annual BESS cost.
Internal losses and losses in the grid are quantified for the different designs. Modelling a battery storage system purely as a finite source/sink of active power in a low-voltage grid, strongly underestimates the potential because of the existing phase unbalance.
The decision variables for design are shown in rows 1–4. For any objective, Inv 1 has the smallest inverter rating (row 1) and Inv 4 the largest. Conversely, battery capacity (row 2) is highest for Inv 1 and smallest for Inv 4. As can be seen in row 5, active power control is symmetric for Inv 1 and Inv 2.
It is seen that the unbalanced inverter designs Inv 3 and Inv 4 manage to equalise the existing voltage unbalance in the peaks. Reactive power control capable inverters only increase the grid losses when used for voltage regulation (row 13). Row 14 shows that the available budget is fully used for all solutions except inverter-only solution H.
Counteracting phase unbalance through an inter-phase power transfer capable inverter, even more so than adding reactive power control, improves the performance of battery storage systems. Storage is considered a key technology in the evolution of the power system [ 1 ].
The chosen inverter design impacts the number of decision variables in the optimisation problem. Each time step, in the simulation horizon has only a single control variable in case of Inv 1; Inv 2 has 2; Inv 3 has 3; Inv 4 has 6.
