Services on Demand Article. It is clear that the DG interconnection significantly changes the traditional concept of distribution systems operation, but it is a challenge for the near future that must be assumed and evaluated with attractive benefit-cost relationships for the different agents involved.

These variables allow evaluating the behavior on the electricity bill of each system customer, and the behavior on financial benefits or penalties for the electric utility due to reliability supplied. Next, the assessment periods of the reliability supplied by electric utility to its customers were simulated.
The system registers the time dedicated to an cret, the type of event, employed human resources and materials. However, if the DG units described in any of the two studies are connected, the utility would receive from its customers through the electricity bill, an annual bonus due to improvements in the reliability supplied. However, it is important to note that the behavior of the incentives and compensations scheme due to cteg reliability supplied, also has a significant impact on the energy bill of passive customers.
This situation has led to implement the concept of small generating units located near to consumption points, incorporating the electrical system backup, as an option of 07 penetration in the electric sector commonly known as distributed rceg DG. The proposed methodology was applied to the IEEE 34 node test feeder, from which it was concluded that the technical benefits of DG interconnection in distribution systems are very significant for both the electric utility and its customers.
Methodology Considerations The DG units are installed directly by customers and these units operate as backup plants, so that when the distribution system is in normal operating conditions, the DG exclusively supplies to crsg customer owns the plant. The proposed methodology consists of a technical and an economic analysis scheme.
CandidateNational University of Colombia, luisluna84 gmail. The results of this analysis are presented in Table creh. This is because the operation scheme designed for this study does not provide great benefits to the system reliability, however, represents a more realistic situation.
This is because the price that could be negotiated between the customer and the electric utility, to improve the reliability, does not cover the additional investment that the customer would do by the purchase of additional generation capacity used as backup for the system.
The generation technologies that wish to be studied for each DG unit, depending on the primary energy sources available at the installation site. On the other hand, the situation is not as beneficial for DG owner customers or for passive customers, due to the high investment and generation costs that still keep most of the DG technologies.
Although implementing DG is not prohibited in Colombia, no market schemes or interconnection technical specifications have been established for DG.

These mechanisms should ensure to the customers that would install these generation sources, that the time to recover their initial investment is shorter or equal than the time calculated for that situation in which the DG capacity represents the peak demand of the respective plant owner. However, such schemes resulted in crdg profitability levels for certain customers, therefore, regulatory measures and bilateral contracts were proposed which would provide a solution for this kind of problem.
For simulating each of these periods, the ceeg simulation procedure for years of analysis was applied.
To implement the proposed methodology, a computational tool was developed using MATLAB and the simulation technique of Monte Carlo sequential of mixed time. On the other hand, if the DG units described in either of the two studies are connected to the system, the utility would receive a certain amount of money per year.
According to the analysis presented above, it was concluded that the interconnection of the DG sources described in the first study, would imply that the incentives and compensations model due to the reliability supplied has greater impacts on the electricity bill of passive customers than the unit cost when the electricity comes from DG units CU dg. The execution of the first study would imply large reductions in the estimated value of the ITADregarding the reference conditions offered by the dead zone.
On the other hand, the ITAD behavior for the first study was fitted to a gamma function of probability density. The feeder’s nominal voltage is Energy supplied by DG sources. These indexes allow assessing the distribution system reliability and the ITAD index.
This methodology consists of two analysis schemes: The worldwide acknowledgment of DG inclusion in power systems and the incentives for optimizing energy resources has received great interest. This information consists of the investment and generation costs of each technology, which are presented in Table 2 Corredor, Applies the OSE Operative Sequence of Events logic, which allows recording of maneuvers operationsload transfers and partial restoration at High and Medium Voltage levels.
This analysis is presented in Table 4. Finally, it applies this methodology to a distribution system and it identifies regulatory strategies when DG interconnection is not profitable.

Iterative Simulation Procedure The computational tool which was designed for implementing the proposed methodology Luna, Parra, creeg summarized below: The incentives scheme is complemented by a compensations scheme to ”worst served” customers, which seeks to reduce the dispersion of reliability supplied by an electric creeg around its mean reliability.
An in-line transformer reducing the voltage to 4. This paper presents a methodology for optimal relocation of transformers in distribution systems. Evaluating and comparing the electricity bill of each customer, for the two operation schemes with and without DG. Simulation methods generate an artificial history of the system by using computational tools, assuming probability distributions for cret component which represent their operation conditions.
The demand model for the load points consists of hourly active and reactive power curves, therefore, the demand for each load point in the test system was adjusted to the behavior of the typical Colombian hourly demand curve.
