Adaptive Power Management Strategy for Effective Volt–Ampere Utilization of a Photovoltaic Generation Unit in Standalone Microgrids

Decentralized Coordination Power Control for Islanding Microgrid Based on PV/BES-VSG

“…Analyzing G pli , finding that if the parameters satisfy the following relations that is given by (20), G pli will become a proportional component, which is equal to γ i . When load demand changes, the inverter output power changes proportionally without dynamic oscillation process.…”

“…3, and (20) can be derived and regarded as a constraint for parameters designed. (20) where, γ i is a introduced constant and The active power control loop in VSG controller is shown in Fig. 4 in details.…”

“…Then, virtual inertia J PVi , and J Bi are designed by considering the overshoot, regulation time of dynamic output power and system stability margin [9]. Meanwhile, the parameters of paralleled inverters should satisfy the constraint conditions shown in (20 It is important to note that, in Part 3 and 4, the active power reference of the VSG controller is P PVi , not P PV_MPPTi .When PV/ BES-VSG unit is in state 1 shown in TABLE I, P PV_MPPTi can't be obtained.…”

“…Switching error of operation mode at any unit will result in the operation failure of the microgrid. Therefore, more adaptive decentralized control methods are expected to address issues above [20], [21].…”

An Innovative Bidirectional DC-AC Converter to Improve Power Quality in a Grid-Connected Microgrid

“…At the moment, power management strategies play an increasingly important role in power quality regulation for micro-grids [9]. In particular, the ultimate challenge is to control power flows to meet various operational objectives (e.g., cost minimization, guaranteed delivery, or security) by adjusting the power flow from or to the main grid, the distribution of energy resources, and the loads' controllability.…”
