Droop Control of Multi-Bus DC Microgrids Towards Economic …
To ensure optimal economic operation of multi-bus DC microgrids (MGs), the optimal power flow (OPF) problem can be formulated to minimize the generation cost. However, due to the weak inertia property of DC MGs, an inappropriate droop gain may lead to instability issuez. To address this problem, this paper proposes an OPF with stability constraints for …
