It is significant to study and improve the flexibility of chemical plants. The flexibility defined as the capability to operate this plant over a range of conditions under external disturbances or inherent uncertainty while satisfying performance specifications by convenient control variables adjustment. The target of this work is to introduce a new approach for designing optimal flexible Heat Exchanger Network (HEN) in a similar fashion of multi-period design depending on similar period durations of worst operating conditions. These worst conditions lie within the uncertainty range in terms of extreme heat load requirements to decrease number of exhaustive iteration and enhance flexibility index from the first design step. This contribution work presents a combined systematic procedure for optimum flexible HEN design based on several mathematical models using linear Interactive and Discrete Optimizer (LINDO) software and Heat Integration Network Targeting (HINT) software. Also provide with comparison and evaluation of existing methods with case study. This presented work resulted in optimum flexible HEN with controllable structure without losing stream targets while keep working at minimum energy consumption levels and achieved minimum Total Annual Costs (TACs) rather than two works in comparison.

Modeling a Local Electricity Market for Transactive Energy Trading of Multi-Aggregators

The present article aims at modeling a day-ahead local electricity market (DA LEM) for transactive energy trading at the distribution level. In this regard, a wide range of distributed energy resources (DERs) in the form of multiple aggregators (AGs) participates in the DA LEM in order to trade energy with the distribution system operator (DSO), the operator of the market. On the other hand, the DSO, as the owner of the system, has the responsibility to procure the required energy of its customers with respect to the technical constraints of the distribution network. To settle the designed local market, a Stackelberg game-based approach is exploited in this research work. In the raised Stackelberg scheme, the leader of the game, the DSO, seeks to maximize its expected profit, while followers of the game, DER AGs, tend to minimize their operating costs. Ultimately, to evaluate the proposed framework, a typical case study is implemented on a modified IEEE-33 bus test system.INDEX TERMS DER aggregator, distribution system operator, local electricity market, Stackelberg game, transactive energy trading.
