This paper has the focus to identify the unknown parameters of solar photovoltaic generators in real time, through the application of a new proposed technic. The identification process is discussed with details, about the four steps of identification. In this regard, the first step explain the experimental data acquisition work, to obtain data from real photovoltaic system. For the second step, a...
It is now becoming increasingly clear that supplying electricity to rural areas is often more economical and cost-effective when it is generated via renewable energy sources rather than grid extension due to prohibitively high costs associated with the latter approach. This paper espouses a better alternative to grid extension for remote communities based on a self-sustaining local economic ecosystem...
The delivery of control reserve by fluctuating renewable energy sources (RES) generators will be important in an energy system with high RES penetration. This paper extends a previously introduced methodology to quantify the possible additional income of different pools of fluctuating RES generators in the negative secondary and tertiary control reserve market in Germany. The updated methodology allows...
Microgrids that are able to work both in grid-connected and islanded modes need a hierarchical structure based on tertiary, secondary and primary controllers, which are fundamental for the maintenance of frequency and stability. In this paper, two types of controllers are formalized and solved as optimal control problems: tertiary and secondary controls. For secondary control two different scaled...
The power generated by the PV generator depends on the irradiance, temperature, and surface conditions. The PV generator has a nonlinear characteristic, and the power has a maximum power point or multi-local maximum power points under different conditions. Various MPPT methods have been reported, in order to confirm the effectiveness of each control method, experimental or simulation analysis is used,...
In order to evaluate the techno-economic performance of Hybrid Energy System for remote rural area electrification, a mixed integer linear mathematical programming model (time-series) has been developed to determine the optimal operation, optimal configuration including the assessment of the economic penetration levels of photovoltaic array area, and cost optimization for a hybrid energy generation...
