Dynamic operation plan of a combined fuel cell cogeneration, solar module, and geo-thermal heat pump system using Genetic Algorithm

Abstract

A chromosome model that simulates the operation patterns of an energy system was introduced into a simple Genetic Algorithm, and a method of dynamic optimization was developed. This paper analyses the operation planning of an energy system that uses in combination a solar power module, proton-exchange membrane fuel cell cogeneration (PEMFC-CGS) with methanol steam reforming, a geo-thermal heat pump, heat storage and battery, commercial power, and a kerosene boiler. The hours of operation of each energy device and the rate of the energy output were calculated by having introduced the analysis program developed by this study. Three objective functions: (a) minimization of operation cost; (b) minimization of the error of demand-and-supply balance; and (c) minimization of the amount of greenhouse gas discharge were given to the optimization analysis of the system. Furthermore, the characteristics of the system operation planning under each objective function are described.

Renewable-energy-based multigeneration systems

“…The system exergy efficiency is calculated with Eq. (11). It has been found that the exergy efficiency increment is not much between system 4 (quadrogeneration) and system 5 (five-product multigeneration).…”

“…Moreover, hybrid systems that are supplied by a combination of renewable sources can be justified for better effectiveness. Obara studied such a hybrid system supplied by geothermal and solar energy. In farming settings, apart from regular products (crops, vegetables, fruits, dairy, etc.…”

Optimal intelligent strategic LMP Solution and Effect of DG in Deregulated System for Congestion Management

“…Also, the reduction in losses is not up to mark; that is why proposed method is introduced so that problem of losses reduction can be more satisfactorily addressed. The demand response should be viewed as an energy tool that can be used in combination with DG and storage units to maintain the equilibrium of the process and optimize the operation of the power system 18‐24 . This article suggests a new peer‐to‐peer (P2P) local energy market architecture and probabilistic LMP for distribution systems central median price allocation and the P2P electricity exchange have each been mentioned as the viable alternatives to mainstream retail quality, strengthening the interaction with presumes share energy capital 25,26 .…”

Energy management of a hybrid photovoltaic system

“…Similarly, Obara 11 investigates a hybrid PVP/Fuel cell/Battery system, where fuel cell is another source besides the PVP.…”

“…In these hybrid systems, PVP and wind energy complement each other and the role of the battery is less important than in the PVP/Battery system. Similarly, Obara [11] investigates a hybrid PVP/Fuel cell/Battery system, where fuel cell is another source besides the PVP.…”
