“…To obtain this, contingency analysis, based on the unit addition algorithm [16], is made use of for relatively smaller Gencos. Where the number of units is higher, a Conditional Probability Capacity Outage Probability Table (CPCOPT) method [15] can be employed to ease the computational effort. For the case of an EMGP 'x', in a state i, where there are 'y' units in service and 'z' units out of service:…”

Abstract--Electric power industry deregulation has brought about the unbundling of generation, transmission and distribution services and as such, new techniques for reliability assessment are being developed to account for the consequent structural changes in the restructured environment through direct analytical techniques or stochastic simulation. To this end, reliability equivalent techniques have been proposed in recent literature and are continuously being improvised upon, especially for the multi-bilateral contracts market structure. Power flow tracing, a potential tool that has so far only been effectively employed in transmission pricing in the open access environment, is deemed to be equally effective in capturing the effect of structural and economic alterations for the purpose of reliability evaluation in the liberalized regime. This paper elaborates on the idea that when used in tandem with reliability equivalent methods, tracing is bound to improve the accuracy of the indices in vogue. The contribution of individual generators and loads to line flows is obtained using a graph theoretic approach, relying on the proportional sharing principle. This information is then proposed to be used in the transmission line Failure Modes and Effects Analysis (FMEA) phase of the established procedure of reliability network equivalents. Comparisons are drawn to highlight the computational as well as accuracy benefits accrued in doing so.

“…For example, WBA is applied to the system state identification by making the capacity outage probability table for TUs considering the participation of WTs [21] and EVs [22]. In [23], an analytical technique has been introduced to model three probabilistic indices of WBA including the health, margin, and risk probabilities, and also its application in the preventive maintenance scheduling of generating facilities. Bulk electric system WBA using sequential Monte Carlo simulation was established in [24].…”

Recently, Wind Turbines (WTs) and Electric Vehicles (EVs) have been integrated into the demand side of many countries. WTs and EVs have uncertainties in electrical energy generation and consumption, respectively. Additionally, Thermal Units (TUs) suffer from random failures. As always, secure power system operation is the main goal of an independent system operator, therefore, these uncertainties should be considered. This paper proposes a two-stage reliability-based model for the economic dispatch of TUs and WTs in the presence of a demand-side response program. At the first stage, the well-being analysis is performed to determine the power generation and spinning reserve of the TUs regarding the timely power generation of WTs. At the second stage, the adoption of the responsive load consumption with the various conditions of the generation system in the power pool market is established using the cost of expected energy not served criterion. This optimization problem is solved at two stages using the genetic algorithm. To validate the proposed model, numerical studies have been applied to the generation part of an IEEE test power system including eleven TUs, one WT, and one thousand EVs.

“…The indices considered in our study are called indices of "wellbeing" of the electrical system. These indices were introduced in 1999 by Roy Billinton [13][14][15] and expressed in terms of healthy, marginal and risky states by use of the following definitions:  Healthy state: The global available power, even if the biggest generation unit is stopped, can cover the required load within adequate operating conditions of the electrical grid.  Marginal state: The global available power is greater than the corresponding hourly load and permits to cover the latter within adequate operating conditions.…”

The photovoltaic sector in Morocco is a serious option for the future. The integration of this type of energy into the grid has a considerable effect on the adequacy of the grid. The objective of this work is to assess the reliability of the Moroccan power grid at the hierarchical level I (HLI: load coverage under the assumption of infinite node) using a non-sequential Monte Carlo simulation in which photovoltaic generation is introduced. In order to lead such a study, a model was used in order to calculate the hourly solar radiation and to determine the time evolution of the electrical power produced by photovoltaic power plants. Finally, we also compared the impact of both PV and wind generations in terms of adequacy of the Moroccan electrical supply
