Coordinated Power Scheme to Mitigate Power Curtailment in the Application of a Microgrid | Chapter 2 | Research Developments in Science and Technology Vol. 8

In certain cases, while the percentage of renewable energy (RE) has grown, the output of RE has decreased. In the present energy market, wind power (WP) curtailments expand along with the percentage of photovoltaics (PV), adding to the challenges encountered by wind farm owners. In this paper, a method of supervisory power coordination is suggested. The main objectives are to prevent more RE electricity from entering the grid, which would cause curtailments. The suggested scheme is to build a grid-connected microgrid system to be run exclusively in response to loads and virtual power plant (VPP) requests such that the system is operated as an independent microgrid when there is no VPP request. This is done in order to make the proposed scheme practical. The efficacy of the proposed approach was examined using computer simulations in the MATLAB/Simulink environment. The verification was done using voltage criteria, including the AC voltage regulation between 6% of the rated AC voltage, the DC voltage regulation between 10% of the rated DC voltage, the power balance according to fluctuations in the loads, and the VPP demands for power. The simulation showed that the suggested technique is viable and warranted, not only for deploying different system configurations but also for minimising power curtailment.

An Integration of Microgrid with Hybrid Renewable Enrgy System and Mitigation of Power Quality Issues | Chapter 14 | Advanced Aspects of Engineering Research Vol. 10

 This chapter demonstrates a microgrid control strategy that integrates wind, photovoltaic (PV), and energy storage (ESS) systems using converters such as MI CUK or SEPIC. Renewable energy sources can produce an erratic output voltage, which will cause the machines to fail. As a result, an energy storage device (ESS) is used to reduce the unpredictability of output voltage. The control strategies and comparative analysis with various converters such as MI CUK and SEPIC converters are demonstrated in this chapter. Mechanical torque can be produced by a wind turbine, and this torque is supplied to PMSM. Mechanical energy is converted to electrical energy by the PMSM. The micro grid may be more stable if it has the option of being connected to the grid or running in island mode. In order to ensure that the micro grid's infrastructure is not subjected to harmful levels of power quality phenomena that do not exist in the national energy grid, the power reliability of micro grids in island operation must be investigated. One of the power material phenomenon is total harmonic distortion (THD) and its individual harmonic components.
