Open Inertia Modelling (OpInMod) is a modelling framework designed to create unit commitment and economic inertia dispatch optimisation problems. Present energy system modelling generators do not consider power system inertia in unit commitment and economic dispatch modelling to assess future energy system pathways. However, maintaining sufficient power system inertia in power systems is the foundation for power frequency controllability. The work at hand describes the functionality and approaches of open source tool OpInMod. The softwares universal design approach increases reuse potential. OpInMod is distributed with a set of examples to test and understand OpInMod

“…Dampak negatif yang dihasilkan dari pemanfaatan sumber energi konvensional terhadap ekosistem lingkungan dalam bentuk emisi gas rumah kaca (GHGs) sebagai hasil proses pembakaran yang menyebabkan pemanasan global, perubahan iklim global, dan kenaikan permukaan air laut menjadi alasan terhadap pentingnya pemanfaatan sumber energi baru terbarukan [2]. Selain itu, karakteristik sumber energi baru terbarukan yang memberikan kondisi energi bersih tanpa menghasilkan emisi gas rumah kaca (GHGs) menjadi alasan juga untuk proses transisi dari pemanfaatan sumber energi konvensional menuju ke sumber energi baru terbarukan [3]. Kondisi ini didukung dengan adanya target pemanfaatan sumber energi baru terbarukan sebesar 20-25% yang terjadi pada tahun 2025 [4].…”

The utilization of briquettes as a source of electricity generation is still low due to the briquette characteristics that have high moisture content. This research analyzes the briquette's potential as a source of electrical energy by utilizing its syngas with microturbine gas. The high quality of syngas can be reached by the optimal combustion chamber design. Therefore, the research aim is to be able to design the optimum combustion chamber for the briquette combustion process to generate the syngas. This research method uses two steps, i.e., the design of the combustion chamber and numerical analysis of the briquette combustion process through Computational Fluid Dynamics (CFD) simulations. Numerical analysis of the combustion process using three types of briquettes with different inorganic waste compositions, i.e., K1 type, K2 type, and K3 type. The research results explain the optimum design of the combustion chamber with a total length dimension of 220 mm, an inlet fuel section, and combustion chamber-syngas pipeline diameter of 50 mm and 75 mm, respectively. In addition, the dimensions of the primary air holes are 7 mm, and the secondary air holes are 5 mm. Type K1 briquettes are capable of producing syngas (kg/s) consisting of 6.9x10-13 CO, 3.04x10-31 H2, and 1.8x10-20 CH4. That syngas composition includes in the criteria of syngas in the microturbines gas that produce electric power of 2.3-2.5 kW. The conclusions explain that the combustion chamber can be added to the microturbine gas component, and K1 type briquette can be a solid fuel.

In recent times renewable energy sources have become an integral part of the modern power grid. As a result, the overall system inertia of the grid has been reduced, thus leading to frequency instability issues such as fast rate of change of frequency. Thus, to compensate for the declining inertia, it is important to carefully select renewable energy generators (REGs) and energy storage systems (ESS) in order to ensure the stability of the power grid, while also controlling greenhouse gases emissions in line with environmental standards. Therefore, this paper proposes an optimal planning model of REGs and ESS, considering the inertia requirement of the grid. The objective function is formulated to minimize the cost of operation, emissions, and investment in new REGs and energy storage units while maximizing the system inertia. The model was developed as a mixed integer linear programming problem and solved using CPLEX solver in GAMS. Finally, the model was validated using a modified IEEE 9-bus system and compared under three scenarios. The results show that in scenario 3 where system inertia is considered in the presence of REGs and ESS, higher system inertia of 8.776 s was achieved at minimal emission and cost, which justifies the aim of the study.
