For the different operation mode of micro-grid, an improved droop control method and a parallel inverter was proposed depending on the study of micro-grid inverter. Grid-connected interface contains a series inverter and a parallel inverter, and can be switched to select different work mode. The parallel inverter can eliminate harmonic, compensate three-phase imbalanced current to improve the quality of the power delivered to the utility grid. In islanding operation mode, the improved droop control strategy was applied, where an integral controller was introduced. So it can reduce the inverter output voltage amplitude. Thereby it can restrain circulation and realize the power of self-distribution. The effectiveness and feasibility are verified by the simulation result.

Grid Operation

Switching control of micro-grid operation modes belongs to short time scale control level, this paper proposes three-tier structure of micro-grid energy management system suitable for switching control of micro-grid operation modes on the basis of the analysis of micro-grid operation mode switching requirements for the control system, and builds micro-grid central control system based on multi-agent technology aiming at the coordinated control of micro-grid operation mode switching, which will effectively enhance the implementation effect of switching control strategy, and play important role in achieving the seamless switching control of micro-grid operation modes.

Grid Operation

The extent to which current is minimized helps in ensuring that the island to grid-connected mode transition is effectively controlled. This applies not only in the short-term but also in the long-term. This is also useful because it helps in maintaining the required level of flexibility as far as the framework of controlling island to grid-connected mode transition is concerned. The integration of interconnectors can also be useful with regard to control of island to gridconnected mode transition. This is because interconnectors can help in identification of shortcomings and existing gaps as far as the framework of island to grid-connected mode transition is concerned. A major reason why the use of interconnectors can help in controlling the island to grid-connected mode transition is that they facilitate continuous monitoring of the grid. This implies that the relevant changes can be identified and incorporated into the island to grid-connected mode transition, in this paper also comparative between two type of the algorithm control MPPT based on the fixed irradiance and temperature.
