This paper presents a study of steady state stability of the Moroccan Power system using bifurcation analysis. More specifically, local bifurcation is considered since, unlike global bifurcation, the system can be analyzed entirely through changes in adequate local stability property of equilibrium for specific buses. The stability property used in this paper is the voltage, as this parameter becomes...
With the ambitious Renewable energy projects, namely Solar, wind and hydroelectric plans, the Moroccan unified power system will undoubtedly face serious problems, especially with regards to the intermittent character of renewable energy sources, and the growing load demand of more than 5%. The impact of these problems may be reduced by proper network development planning, based on accurate simulation...
This article aims at developing long term electricity forecasts for Morocco, using Non Linear Autoregressive model (NLARX) based on a special class of Artificial Neural Networks (ANN), namely Wavelet Networks. This model provides more accurate forecasting results thanks to the nature of the used neural networks structure that has been developed in other fields. The obtained results will help design...
This paper presents an optimization method for the power contract under the High Voltage tariff structure in Morocco. The optimization is based on minimization of the billing cost, formulated as an objective function that takes into account the power charges, the excess of the power contract charges and the bi-seasonality of the tariff structure. This method is applied to the real case study of the...
Electricity demand forecasting is vitally important for power production companies. It has many applications, including energy production scheduling, maintenance and operation of electric network, elaboration of accurate investment and development plans for transmission and distribution networks, negotiation of PPAs (Power Purchase Agreements) and purchasing fuels at optimal costs. Over the last decades,...
This article aims at optimizing the choice of the power rating of the 33/225 KV transformers of the wind farms under the Moroccan program of 850 MW wind, important part of the Moroccan renewable energy strategy up to 2020. This optimization is based on a technical and economic approach that integrates parameters such as turbine power distributions, selling price of the kWh and discount rate. The power...
