PV/Diesel Hybrid System for Fuel Production from Waste Plastics RecyclingIJMER
The treatment of wastes has become one of the most important concerns of modern society.
Converting waste plastic into gasoline and diesel fuel through a highly effective low-cost pyrolysis
process is a promising technology. In this paper PV/Diesel/Battery hybrid system is suggested to fulfill
the load demand of waste plastic recycling pyrolysis process. A Mathematical and simulation models
using MATLAB/ SIMULINK software for the hybrid PV/Diesel/Battery system components have been
developed. Also, this paper presents a control strategy using Artificial Neural Network Controller
(NNC) technique for coordinating the power flow among the different components of the
PV/Diesel/Battery hybrid system. The results indicate that the proposed control unit using NNC can be
successfully used for controlling the power system for the waste plastic recycling pyrolysis process.

An efficient modified cuk converter with fuzzy based maximum power point trac...Asoka Technologies
To improve the performance of photovoltaic system a modified cuk converter with Maximum Power Point Tracker (MPPT) that uses a fuzzy logic control algorithm is presented in this research work. In the proposed cuk converter, the conduction losses and switching losses are reduced by means of replacing the passive elements with switched capacitors. These switched capacitors are used to provide smooth transition of voltage and current. So, the conversion efficiency of the converter is improved and the efficiency of the PV system is increased. The PV systems use a MPPT to continuously extract the highest possible power and deliver it to the load. MPPT consists of a dc-dc converter used to find and maintain operation at the maximum power point using a tracking algorithm. The simulated results indicate that a considerable amount of additional power can be extracted from photovoltaic module using a proposed converter with fuzzy logic controller based MPPT
Integrated Energy System Modeling of China for 2020 by Incorporating Demand R...Kashif Mehmood
Electricity and heat energy carriers are mostly produced by the fossil fuel sources that are
conventionally operated independently, but these carriers have low efficiency due to heat losses. Moreover,
a high share of variable renewable energy sources disrupts the power system reliability and flexibility.
Therefore, the coupling of multiple energy carriers is underlined to address the above-mentioned issues that
are supported by the latest technologies, such as combined heat and power, heat pumps, demand response,
and energy storages. These coupling nodes in energy hubs stimulate the conversion of the electric power
system into the integrated energy system that proves to be cost-effective, flexible, and carbon-free. The
proposed work uses EnergyPLAN to model electricity, district, and individual heating integrated energy
system of China for the year 2020. Furthermore, the addition of heat pumps, thermal storage, and demand
response is analyzed in different scenarios to minimize the annual costs, fuel consumption, and CO2
emissions. Technical simulation strategy is conducted for optimal operation of production components that
result in the reduction of the above-mentioned prominent factors while calculating the critical and exportable
excess electricity production. The simulation results demonstrate that demand response and thermal storage
significantly enhance the share of variable renewable energy sources. In addition, it substantially reduces the
annual costs and fuel consumption, while heat pump increases the system efficiency
