6 FAQs about [Random Power Flow Microgrid]

What is a microgrid (MG)?

1. Introduction A microgrid (MG) is a promising paradigm of electric power systems which integrates distributed generation (DG) units, energy storage systems and controllable loads to maintain the power supply in a defined area . The applications of power electronic devices in MGs have improved the flexibility of power system operation.

What is the penetration coefficient of microgrids in power systems?

The penetration coefficient of microgrids in power systems, as well as the high uncertainty of these sources, requires an analysis of probabilistic methods. These types of energy sources are inherently uncertain and bring many unknowns to the power system.

What is probabilistic power flow?

Probabilistic power flow (PPF) is an effective method to evaluate the steady state of power systems with uncertainties [10]. The Monte Carlo simulation (MCS) [11], [12], [13], point estimate method (PEM) [14], [15], [16] and cumulant method (CM) [17], [18] are widely used in PPF calculation.

What is the distribution of the optimal power flow (POPF)?

One of the most important aspects to be analyzed is the distribution of the probabilistic optimal power flow (POPF). This research examines some methods for the distribution of possible loads in power systems, namely the Monte Carlo method (MCM), the two-point estimation method (2PEM), and the three-point estimation method (3PEM).

Can a PPF method improve the performance of multi-MGS distribution systems?

To improve the performance of existing methods, a novel PPF method for multi-MGs distribution systems with incomplete network information is proposed. This method is explored based on both deep learning and mechanism models.

Where should a microgrid be installed?

Network line specifications According to the planning policy, and considering the increase in energy production, microgrids should be installed near buses 5, 7, and 8. Network buses can also be selected for connection. The wind turbine, with a rated power of 2.5 MW, starts working at 2.5 m/s, has a rated speed of 13 m/s, and stops at 25 m/s.
