The conventional grid refers to the traditional electrical grid that operates in a unidirectional manner, where electricity flows from generators to substations and eventually to consumers. It is characterized by outdated infrastructure and challenges in meeting current energy demands, load balancing, and adapting to growing energy needs.

Conventional power system coordination includes the primary and back-up protection [5,6]. The main parts of the power system (grid), including generation, high voltage transmission line, and distribution, have to be adjusted to appropriate settings. The protection challenges significantly increase with the growth of the power system.
A look at the traditional energy grid. The conventional grid has been around for a long time. The first real grid was built in 1896 taking power from Niagara Falls hydro to Buffalo. The conventional grid design was based on the ''economics of scale'' of large, centralised power generators. These were connected to bulk power transmission

Integration of distributed renewable energy systems into the smart grid. Ghanim Putrus, Edward Bentley, in Electric Renewable Energy Systems, 2016. 20.2 Conventional power generation. Conventional power plant is the general term applied to the production of electrical energy from coal, oil, or natural gas using the intermediary of steam. The generator is usually a
The subsystem represented in Figure 1(a) could be one of a final user of the electric energy of a full power system. The subsystem represented in Figure 1(b) could be one of a small power plant working as distributed generation (DG). Most of these power systems operate only when connected to a full power system.
In the early stage, power was generated by DC source and grids were isolated from the load, therefore DC power is transmitted over a short distance only because of higher power loss in the transmission line. Traditional power grids face a lot of challenges in managing power system especially in the generation, transmission, and distribution.

At this stage, by a grid, we mean the conventional large-scale power system setup explained above. Cost involvement in the expansion of conventional power systems: As the power demand continuously increases, so is the necessity to build new power plants and transmission lines. This is a very hectic task in terms of the location''s geography, the
Flexibility: The electricity grid allows a power system to use a diversity of resources, even if they are located far away from where the power is needed. For example, wind turbines must be built where the wind is the strongest; the grid allows for this electricity to be transmitted to distant cities.
A steam turbine used to provide electric power. An electric power system is a network of electrical components deployed to supply, transfer, and use electric power. An example of a power system is the electrical grid that provides power to homes and industries within an extended area. The electrical grid can be broadly divided into the generators that supply the power, the

Despite depending upon a single energy source, hybrid energy systems (HESs) based on conventional and renewable energy sources, energy storage elements, and the load consumption in a single system offer promising advantages over a conventional power system. An HES is usually an off-grid system consisting of renewable energy technologies like
Power grids are critical infrastructure in modern society, and there are well-established theories for the stability and control of traditional power grids under a centralized paradigm. Driven by environmental and sustainability concerns, power grids are undergoing an unprecedented transition, with much more flexibility as well as uncertainty brought by the growing penetration
For instance, in China, the power grid company is required to guarantee the purchase of all renewable power generated. 1 However, it is worth discussing whether this is an economically effective policy if the integration cost is considered. the impact of integrating VRE with conventional power system is quantified in this paper. The
The historical design of the grid, which may be described as supplying end users with centralized electricity generated and a conventional one-way high transmission loss system, is evolved into a more discrete, dynamic system that is defined by a two-way flow of information and power (both centralized and distributed).
