Uncertainty management in decision-making in power system operation

Abstract

I. AbstractDue to the penetration of renewable energy resources and load deviation, uncertainty handling is one of the main challenges for the power system. Therefore, the need for accurate decision making in a power system under the penetration of uncertainties is essential. However, decision-makers should use suitable methods for uncertainty management. In this chapter, some of uncertainty modeling methods in power system studies are analyzed. At first, multiple uncertain parameters which the power system deals with them are introduced, then, some useful uncertainty modeling methods are introduced. To show the uncertainty modeling process and its effect on the decision making, a microgrid consisting multiple uncertain parameters is considered, and stochastic scenario-based approach is used for uncertainty modeling. The scheduling of microgrid in presence of different types of uncertainty is solved from the profit maximization point of view. |The simulation results are presented for 33-bus microgrid which shows the effectiveness of the proposed method for decision making under high level of uncertainty.

“…It should be noted that Weibull and Normal distribution function are used to model the wind power, load, and price uncertainties. More information can be found in [63,64]. This paper presumes that 10% of the total local demand contributes to DRP as in [65,66].…”

“…Meanwhile, the penetration of renewable power generation, and load variation, is one of the most common challenges faced by MGs operation [31]. In [32], a probabilistic optimization approach was investigated for optimal operation of CHP-based MGs integrated with DRP, with the load, energy price, and wind power output uncertainty.…”

“…As it is not possible to discharge to the CAES, it operates in the simple cycle mode to generate electricity as a micro-turbine. The restrictions of the CAES scheme are given in ( 24) - (31). The logical constraint that separates the CAES operation mode at each time is represented by (24).…”
