Evaluation of the reserve capacity in a grid supplied by intermittent energy sources

Abstract

Renewable energy (RnE) is a key element for the national energy strategies in the world especially for emerging and developing countries. Morocco, which has no conventional energy resources, depends almost entirely on the international primary energy market, to satisfy its growing demand inherent to its economic growth and its demographic progression, the country import the majority for its supply of energy sources. Morocco has implemented an important energy strategy that supports the country's transition to RnE and energy efficiency that generalises across all consumer sectors of the economy (housing, transport, industry). However, the integration of renewables into power systems and the development of adequate reserve capacity are seem to be significant for these strategies in particular in the wind power case. This study presents the impact of the smoothing effect on reserve capacity and energy savings available through the net balancing between different climate zones to achieve fuel cost savings and reduce CO 2 emissions.

Construction and Optimization of Dynamic Assessment Indicators for Distribution Grid Carrying Capacity with High Proportion of Distributed Resource Connections

“…To analyze the size of the distribution network, the load-carrying capacity of distributed energy access first needs to clarify its influencing factors, and the influencing factors limiting its load-carrying capacity mainly include equipment line thermal stability, node voltage, protection configuration, and power quality [9][10]. In the actual analysis and measurement process, the above-influencing factors are mapped to the relevant constraint indicators, including thermal stability reverse load ratio, voltage deviation calibration, short-circuit current calibration, and harmonic calibration [11].…”
