The development of smart grids (SG) in the electrical network is the subject of many studies nowadays. This new technology seems to be as an additional tool and the perfect solution which the D.R. Congo could use to achieve the objectives of the efficient management of electrical energy, electrical network security, and the inclusion of renewable energy sources. The rise of these new networks brings together many economic issues. This study is essentially focused on the incapability of the National Electricity Company (SNEL) which still retains the monopoly of production and distribution of energy to individuals, industries and mining companies. The incorporation of a system of control and management of the two-ways energy flow between the sources of electricity production and users via an intelligent distribution network, considering several specific constraints and performance required, will allow us to highlight the influence of intelligence in a distribution network as complex as that of the city of Lubumbashi. This study reviews the challenges of renewable energies in the environment of the city of Lubumbashi, the modeling of the distribution network, the introduction of intelligence control in the network and simulation using computer tools to see the contribution of these results to the entire electrical system. Finally, the integration of new renewable energy sources associated with its monitoring system is planned to stabilize this network by increasing the efficiency of the system with 25 percent in power quality.

“…For the one with no high-frequency transformers, the suggested WECU topologies consists of WT-generator (e.g. PMSG) interfaced: by a three-phase diode bridge rectifier cascaded with a single-switch DC-DC converter [42][43][44][45][46], by a three-phase diode bridge rectifier cascaded with an interleaved single-switch DC-DC converter [47], by a conventional three-phase full-bridge voltage-source converter (VSC) [28,48,49], by a three-phase neutral-point-clamped (NPC) converter [50], by a half-bridge VSC [51], by a thyristors converter [52], and by a current SC (CSC) with self-commutated switches [53].…”

“…A cascade connection of a diode bridge rectifier and a single-switch DC-DC buck converter was proposed in [42] as a potential converter topology in WECUs for lowvoltage application. From recent studies [43][44][45][46], a three-phase diode bridge rectifier cascaded with a single-switch DC-DC boost converter was investigated. Another option was to use the interleaved single-switch DC-DC boost converter instead of the single-switch DC-DC boost converter in the WECUs [47], which reduces switch stresses and the volume of magnetic components in the DC-DC boost converter.…”

Traditionally, the network composition of offshore wind farms consists of alternating current (AC) grid; all outputs of wind-energy conversion units (WECUs) on a wind farm are aggregated to an AC bus. Each WECU includes: a wind-turbine (WT), a generator and a power transformer. For a DC collection grid, all outputs of WECUs are aggregated to a DC bus. The transformer in each WECU is replaced by a converter which is more compact and smaller in size compared with the transformer, thus simplifying the wind farm structure. The use of AC offshore grids instead of DC offshore grids is mainly motivated by the availability of protection devices. Efficient solutions to protect DC grids have already been addressed. Presently, there are no operational DC wind-farms, only small-scale prototypes are being investigated worldwide. Therefore, a suitable configuration of the DC collection grid, which has been practically verified, is not available yet. This study discussed some of the main components required for a DC grid including: the WT-generator models, the control and protection methods, the platform structure, and the feeder configurations. The key component of a DC grid is the converter; therefore, this study also reviews some topologies of converter suitable for DC-grid applications.
