A classification from previous content about the link between countries, as well as the feasibility study and what are its economic and technical advantages
1- Types of connection:-
- Open linkage and closed linkage (linking them, open linkage and closed linkage), through the open linkage and external linkage, because the circuit breakers connect the linkage between the electrical linkage channels in the moments that follow the linkage channels. There is a need to join the forum, and ID as such between Tunisia and Algeria, as well as between Syria, Lebanon, Syria and Jordan.
Synchronous connection with simultaneous connection with connection when two electricians are connected by alternating current, which leads in the event of a problem on the network, simultaneous connection when connecting two electricians by alternating current, which can work in the environment of the digital alternating network, but if it connects networks With connected frequencies, the binding is asynchronous.
C) - Energy linkage, energy linkage, energy linkage and solar energy: Electricity is included in electricity prices, because of the cost of electricity. Savings equally between the two states. The exchange can develop between the two countries, due to the presence of gas as an energy source, such as the presence of natural or the presence of new generation plants, the source of access in the second country.
2- Feasibility studies:-
2014 Feasibility studies for electrical interconnection projects between two countries (or more) of four phases
In the first stage, the data is collected in the economic and electricity data in the concerned countries, including the forecasts of the loads, electronic programs, and the generation of new stations. In this stage, sharing bases for networks such as the percentage and percentage of unmet energy are also selected.
The second stage provides access to opportunities to have the opportunity to have access to all of these energy solutions. Reach the final product to the value of determining the technical aspects
The third stage, in which detailed technical studies are prepared for each alternative, with regard to the ability of the associated system to remain in a balanced state in the event of any network malfunctions. At this stage, the number of alternatives is reduced to about two alternatives.
The fourth and final stage of the study, in which economic studies are prepared for the cost of the two alternatives that were identified in the third stage in order to choose the best of them, and to set specifications for the equipment required to achieve the connection using the chosen alternative.
3- Economic and technical advantages:-
A) - It allows reducing the spare capacity (the standby capacity represents the difference between the available generation capacity and the maximum load) installed in each network, and thus leads to a reduction in the capital investments necessary to meet demand without compromising the degree of safety and reliability in the linked networks, given that the interconnection line constitutes a capacity Additional generation for linked networks.
b) It allows reducing the rotating reserve (the rotating reserve at a moment represents the difference between the total capacities of the synchronous generating units on the network and the maximum load at that moment) while maintaining the same level of network security, and thus reducing operating costs, because the linked networks can benefit from Of the entire rotating reserve available in those networks, as the possibility of a sudden malfunction at the same time in more than one network is very small.
c) - It makes the interconnected networks one network more extensive with more balanced tension and better static and dynamic stability, as the linked network is better than the single network to restore its stability after disturbances or accidents
the big one.
D) - It is allowed to benefit from the different generation systems when one of the hydroelectric generation networks is dominant, and the other network is dominated by thermal generation, as it is possible to reduce the impact of years of water scarcity in countries that depend
on hydro power.
e) It is allowed to take advantage of the difference in the seasonal, weekly and daily peak times, as the peak loads of the linked network are usually less than the sum of the peak loads of the separate networks. This reduces the generation costs of kilowatt-hours during peak times as less efficient generating units, which are usually used to meet peak loads, are not required to operate.
In addition to the foregoing, a number of important environmental impacts are added, in particular reducing emissions of waste gases by using the most efficient generation units, as well as reducing emissions and gases polluting the environment and acid rain as a result of reducing the number of operating generating units
