The viability of Variable Renewable Energy (VRE)-investment strategies depends on the response dispatchable producers to satisfy net load. We lack a simple research tool with sufficient complexity represent major phenomena associated integration high shares VRE and their impact system costs. develop minimization cost allowing one quantify decompose value depending an aggregate production. Defin...

In the paper, a new method of long-term planning operation and development distribution system, taking into account operational aspects such as power flows, losses, voltage levels, energy balances, is presented. The developed allows for allocation selection Renewable Energy Sources (RES), control storage (ES), curtailing RES production (EC), grid (GD). Different types loads are considered, repr...

Maintaining transient stability is crucial in power system operation. Transient mainly affected by the generation amount of study region, as well transmission topology. Several countermeasures can be taken for stability, but usually used control means are generating unit tripping and curtailment. In terms economic operation, one say that solution more beneficial. To maintain east coast region K...

Clean and low-carbon energy represented by wind power photovoltaic will develop rapidly form a new system with high proportion of renewable energy. In the context economy, how to make reasonable planning for flexibility resources is crucial development systems. this paper, we establish multi-flexibility resource model based on low carbon economy considering “source–load–storage”. First, ladder-...

A novel control strategy to manage the integration of a wind turbine (WT) and an energy storage unit existing stand-alone microgrid servicing oil gas (O&G) rig is topic this paper. The includes primary secondary controller that, using battery in tandem with WT, does not require any dump load (A). management system (EMS) which uses estimated production other specific local information size a...

The optimal operation of microgrids is great significance for the sake efficient and economical management its energy resources. microgrid system should plan to operate while simultaneously considering electric thermal load. present study proposes minimize costs operating an industrial microgrid. In fact, planning supply among critical issues that distribution companies deal with daily in compe...

the intermittency and variability of these permeated Distributed Generators (DGs) could critically cause many security and economy risks to distribution systems. This paper applied a certain mathematical distribution to imitate the output variability and uncertainty of DGs. And then, four risk indices EENS, PLC, EFLC and SI were established to reflect the system risk level of distribution syste...
