Innovative load management through DSM: This paper introduces a simple and practical approach for load management in isolated microgrid systems, particularly in rural areas. This involves classifying electrical loads based on user-defined priorities and managing them dynamically to optimise energy usage.
The solar incidence, wind speed, and the loads’ profile are taken into account as entries of the problem, modifying the scenario of load and generation during the islanding mode. So, for each instance, the load flow for the microgrid is solved. After the load flow convergence, the frequency and voltage are verified.
In this sense, the possibility to use load shedding strategies, considering the restriction of the continuous energy supply to high priority loads is a motivation of this paper. The operating point of a microgrid along time may be adequately determined by employing a proper load flow at each point.
Then, a load shedding scheme for under-frequency was proposed and tested. Hence, the microgrid can operate in an emergency, preserving the operation limits by load shedding schemes. Associated with the performance of load shedding schemes, a MCS was used to give an estimative of the load shedding. The indices LOLP and EENS were monitored.
A novel control mechanism is presented for rural microgrids, standing out in the current literature with its advanced approach to load prioritisation and energy allocation. The system's main goal is to maximise energy supply to essential loads while effectively managing available resources.
