“…challenges in stability [10]. Therefore, energy systems require strategies to improve their flexibility and stability, and thus achieve the integration of these intermittent resources and meeting the requirements of the demand [11], [12]. One of the technologies currently used, to balance intermittency and increase system flexibility, is gasfired thermal generators [13].…”

The energy transition from fossil-fuel generators to renewable energies represents a paramount challenge. This is mainly due to the uncertainty and unpredictability associated with renewable resources. A greater flexibility is requested for power system operation to fulfill demand requirements considering security and economic restrictions. In particular, the use of gas-fired generators has increased to enhance system flexibility in response to the integration of renewable energy sources. This paper provides a comprehensive formulation for modeling a natural gas supply network to provide gas for thermal generators, considering the use of wind power sources for the operation of the electrical system over a 24-hour period. The results indicate the requirements of gas with different wind power level of integration. The model is evaluated on a network of 20 NG nodes and on a 24-bus IEEE RTS system with various operative settings during a 24-hour period.

“…Thus, multiple economic models related to the electricity sector are being developed recently that consider elements such as: consumersupplier relationship, the capacity of the consumer to change his/ her role (producer-prosumer), the form of consumer participation (active or passive), the intensity of collaboration between peers (with contracts or not), the inclusion of new production assets such as renewable energy (Obando et al, 2020), energy storage systems (Cantillo and Moreno, 2021), and demand response (Moreno et al, 2019), and the ownership and channels transfer used (blockchain among others) (Acquier et al, 2019;Athanassiou and Kotsi, 2018;Ertz et al, 2019;Ferraro and Conway, 2020;Garcia-Garcia et al, 2020;Hamari et al, 2016;Menor-Campos et al, 2019). All these elements were considered through different models made with different computing tools (Moreno-Chuquen and Cantillo-Luna, 2020).…”

Recently, several authors and reports inform about peer-to-peer transactions of goods and services. Usually, the electricity markets work trading energy at large scale in wholesale electricity markets. Given the integration of distributed energy resources such as PV generators, storage at small scale, demand response and electric vehicles then there are new options to trade energy at small scale by focusing in the producer-consumer relationship. This derives in alternatives based on peer-to-peer (P2P) electricity markets to trade energy employing tools as the blockchain and deployment of distributed energy resources (DERs). This paper presents a framework to trade energy at small scale with a flexible hybrid model of P2P based on transactions between communities and peers, for each period of time, each peer can change its role, the prosumer and producer peers can offer their generated energy. The consumer peers can adjust their consumption behavior based on price and quantity. Thus, the role of the community manager comes into play to associations between peers as an intermediary of the community and the grid. Therefore, a model of transactions with P2P offers was developed for different structures and sales prices. Finally, the framework to trade energy in a hybrid P2P model is evaluated in a demand curve considering a 24-h period for several cases.

Comparative Performance of Multi-Period ACOPF and Multi-Period DCOPF under High Integration of Wind Power

et al. 2021

Today, the power system operation represents a challenge given the security and reliability requirements. Mathematical models are used to represent and solve operational and planning issues related with electric systems. Specifically, the AC optimal power flow (ACOPF) and the DC optimal power flow (DCOPF) are tools used for operational and planning purposes. The DCOPF versions correspond to lineal versions of the ACOPF. This is due to the fact that the power flow solution is often hard to obtain with the ACOPF considering all constraints. However, the simplifications use only active power without considering reactive power, voltage values and losses on transmission lines, which are crucial factors for power system operation, potentially leading to inaccurate results. This paper develops a detailed formulation for both DCOPF and ACOPF with multiple generation sources to provide a 24-h dispatching in order to compare the differences between the solutions with different scenarios under high penetration of wind power. The results indicate the DCOPF inaccuracies with respect to the complete solution provided by the ACOPF.
